Calculate the mean and the standard deviation of the number of forms with mistakes she should expect to find.
The IRS employee checked 25 randomly selected forms and didn't find any mistakes. Does this provide convincing evidence to cause her supervisor to believe that she is missing mistakes? Explain.

Answers

Answer 1

Probability of exactly one error in 10 forms: Use binomial distribution with n = 10 and p = 0.08..Mean and standard deviation of forms with mistakes: Calculate using expected value and standard deviation formulas for a binomial distribution.

To calculate the probability that exactly one form has an error out of 10 randomly selected forms, we use the binomial probability formula: P(X = k) = (n C k) * p^k * (1-p)^(n-k), where n is the number of trials, p is the probability of success, and k is the number of successes. In this case, n = 10, p = 0.08, and k = 1. Plugging in these values, we can calculate the probability as P(X = 1) = (10 C 1) * (0.08)^1 * (1-0.08)^(10-1).

The mean (expected value) of the number of forms with mistakes can be calculated as μ = n * p, where n is the number of trials and p is the probability of success. In this case, n = 25 and p = 0.08. The standard deviation can be calculated as σ = sqrt(n * p * (1-p)), where sqrt represents the square root. Plugging in the values, we can calculate the mean and standard deviation.

Finding no mistakes in 25 randomly selected forms does not provide strong evidence to conclude that the employee is missing mistakes. The probability of not finding any mistakes in 25 forms can be calculated using the binomial distribution with parameters n = 25 and p = 0.08. If the actual proportion of mistakes is 8%, it is possible to observe a sample without mistakes due to random chance. To draw a more reliable conclusion, a larger sample size or additional evidence would be needed.

Answer:

∠ W = 51°

Step-by-step explanation:

Since WX is the diameter , then

∠ WYX = 90° ( angle in a semicircle )

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Answers

Correct question:

The experimental probability that Cindy will catch a fly ball is equal to 3/7. About what percent of the time will Cindy catch a fly ball?

Answer:

42.9%

Step-by-step explanation:

Given that:

Experimental probability of catching a fly is 3/7

This can be interpreted as : Out of 7 tries, Cindy caught a fly only 3 times

Expressing this as a percentage :

3/7 * 100%

0.4285714 * 100%

42.857%

= 42.9%

Hence, Cindy will catch a fly at about 42.9% of the time

As part of a larger study investing attitudes towards relationships, a survey was administered to unmarried, currently married, and formerly married adults. First married adults had more positive perceptions of marriage than singles or remarried adults, F(2, 39) = 5.34, p = 042

Answers

It is clear that First-married adults had more positive perceptions of marriage than singles or remarried adults.

Attitudes towards relationships are often studied to determine how they affect people's perception of them. A survey was given to unmarried, currently married, and formerly married adults as part of a broader study of attitudes toward relationships. In this study, it was discovered that first-married adults had more positive attitudes toward marriage than single or remarried adults. The statistical values from the study are provided below:First married adults had more positive perceptions of marriage than singles or remarried adults, F(2, 39) = 5.34, p = 0.042.F stands for F-test, which is a statistical test used to compare whether the means of two or more groups differ from each other significantly. Here, the F-test indicated that there was a statistically significant difference in the attitudes of first-married adults, unmarried adults, and remarried adults towards marriage. Additionally, the p-value is 0.042, which indicates that there is a statistically significant difference between the groups' attitudes towards marriage.

The sentence given "First married adults had more positive perceptions of marriage than singles or remarried adults, F(2, 39) = 5.34, p = 042" is a claim made in the larger study that was conducted investigating attitudes towards relationships.

The F(2, 39) = 5.34 indicates that the claim is statistically significant and the p-value is less than 0.05, which is the generally accepted level of significance, indicating that the findings are not due to chance.

The terms "part" and "positive" are related to the study but do not specifically apply to this claim. The claim made in this sentence is that first-married adults had more positive perceptions of marriage than singles or remarried adults. The F(2, 39) = 5.34 indicates that the claim is statistically significant. F-statistic is the ratio of between-group variance to within-group variance. Here, the between-group variance is the variance among the perceptions of different types of adults (i.e., first-married, singles, remarried) and the within-group variance is the variance within each group. Since the F-value is statistically significant, we can reject the null hypothesis and accept that there are differences in perceptions of different types of adults. The p-value is the probability of finding such results by chance. Here, the p-value is less than 0.05, which is the generally accepted level of significance, indicating that the findings are not due to chance.

Classify the sequence as arithmetic or geometric; then write a rule for the nth term. 900,450,225,

Answers

Geometric sequence with a common ratio of 1/2. Rule for the nth term: an = 900  (1/2)^(n-1).

A sequence is considered arithmetic if the difference between consecutive terms is constant, and it is geometric if the ratio between consecutive terms is constant. In the given sequence, we can observe that each term is half of the previous term, indicating a constant ratio of 1/2.

To find the rule for the nth term of a geometric sequence, we start with the first term and multiply it by the common ratio raised to the power of (n-1), where n represents the position of the term. In this case, the first term is 900, and the common ratio is 1/2. Therefore, the rule for the nth term of the sequence is an = 900 (1/2)^(n-1).

Using this rule, we can find any term in the sequence by substituting the corresponding value of n into the formula. For example, the third term can be found by setting n = 3: a3 = 900 (1/2)^(3-1) = 225.

Which of the following represents the function f(x) = 5x^(2) + 20x + 25 in vertex form. Identify the vertex.

Answers

The function f(x) = 5x^2 + 20x + 25 can be rewritten in vertex form as f(x) = 5(x + 2)^2 + 5, and its vertex is located at (-2, 5).

To rewrite the function f(x) = 5x^2 + 20x + 25 in vertex form, we complete the square. The vertex form of a quadratic function is given by f(x) = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's complete the square:

f(x) = 5(x^2 + 4x) + 25

To complete the square, we need to add and subtract (4/2)^2 = 4 to the expression inside the parentheses:

f(x) = 5(x^2 + 4x + 4 - 4) + 25

Rearranging the terms:

f(x) = 5((x^2 + 4x + 4) - 4) + 25

Now we can factor the perfect square inside the parentheses:

f(x) = 5((x + 2)^2 - 4) + 25

Expanding and simplifying further:

f(x) = 5(x + 2)^2 - 20 + 25

f(x) = 5(x + 2)^2 + 5

Therefore, the function f(x) = 5x^2 + 20x + 25 in vertex form is f(x) = 5(x + 2)^2 + 5. The vertex is given by the coordinates (-2, 5).

In recent years the interest rate on home mortgages has declined to less than 6.0 percent. However, according to a study by Federal Reserve Board the rate charge on credit card debit is more than 14 percent. Listed below is the interest rate charged on a sample of 10 credit cards. 14.6 16.7 17.4 17.0 17.8 15.4 13.1 15.8 14.3 14.5 Is it reasonable to conclude the mean rate charged is greater than 14 percent? Use the 0.01 significance level. Assume the interest rate on home mortgages is normally distributed.

Answers

We can conclude that, at the 0.01 significance level, there is sufficient evidence to support the claim that the mean rate charged on credit cards is greater than 14%.

How to calculate the value

The test statistic is calculated as follows:

t = (x - μ) / (s / √n)

In this case, the sample mean is 15.66%, the sample standard deviation is 1.544%, and the sample size is 10. Plugging these values into the formula for the test statistic, we get:

t = (15.66 - 14) / (1.544 / √10)

= 3.4

The critical value is the value of the test statistic that separates the rejection region from the non-rejection region. The critical value for a two-tailed test with a significance level of 0.01 and 9 degrees of freedom (10 - 1 = 9) is 2.821.

Since the test statistic (3.4) is greater than the critical value (2.821), we reject the null hypothesis. This means that there is sufficient evidence to conclude that the mean rate charged is greater than 14%.

We can conclude that, at the 0.01 significance level, there is sufficient evidence to support the claim that the mean rate charged on credit cards is greater than 14%.

(ii) Making the same assumptions again, how many operators should there be in the combined centre to ensure sufficient capacity to meet 95% of demand? (20 marks)

Answers

Given information: The hourly number of emergency telephone calls coming in to a police command and control center has approximately a normal distribution with a mean of 130 and standard deviation of 25. One operator can deal with 24 calls in an hour.

a) The probability that 6 operators will be able to deal with all the calls that arise in an hour is 0.7642.

b) The number of operators should be 203 to ensure that there is sufficient capacity to meet 95% of demand.

c) (i) The probability that 12 operators will be able to deal with all the calls that arise in an hour is 0.7852.

(ii) The number of operators should be 336 to ensure that there is sufficient capacity to meet 95% of demand.

a) Probability that 6 operators will be able to deal with all the calls that arise in an hour.

Mean, µ = 130, Standard Deviation, σ = 25.

Operator can deal with in an hour, n = 24.

Let X = number of emergency calls coming in an hour.

The number of emergency telephone calls coming in to a police command and control center in an hour can be assumed to be Poisson with λ = 130.

Since each operator can handle 24 calls in an hour, therefore, the number of operators required to handle all the calls can be obtained as follows: [tex]$$\frac{X}{24}$$[/tex].

This can be converted to a Standard Normal Variable Z using the formula:[tex]$$Z=\frac{(\frac{X}{24}-\mu)}{\sigma}$$[/tex].

Probability that 6 operators will be able to deal with all the calls that arise in an hour can be calculated as follows:

[tex]$$\begin{aligned} \frac{X}{24} &\leq 6 \\ X &\leq 6 \times 24 \\ X &\leq 144 \end{aligned}$$[/tex]

Now, we need to find the probability of Z ≤ [tex]$$(\frac{144}{24}-130)/25=0.72$$[/tex].

Using normal distribution tables, we get P(Z ≤ 0.72) = 0.7642.

Hence, the probability that 6 operators will be able to deal with all the calls that arise in an hour is 0.7642.

b) To find the number of operators should there be to ensure that there is sufficient capacity to meet 95% of demand.

Let X = number of emergency calls coming in an hour.

The number of emergency telephone calls coming in to a police command and control center in an hour can be assumed to be Poisson with λ = 130.

Since each operator can handle 24 calls in an hour, therefore, the number of operators required to handle all the calls can be obtained as follows:[tex]$$\frac{X}{24}$$[/tex].

This can be converted to a Standard Normal Variable Z using the formula:[tex]$$Z=\frac{(\frac{X}{24}-\mu)}{\sigma}$$[/tex].

To ensure sufficient capacity to meet 95% of demand, we need to find the value of X such that: P(X ≤ x) = 0.95.

Using the Z table, we can find that the probability of Z ≤ 1.645 is 0.95.

Now, we can use the formula:

[tex]$$\frac{X}{24}-130/25=1.645$$[/tex]

[tex]$$X= 1.645\times 25\times 24+130$$[/tex]

[tex]$$X=202.63$$[/tex]

Therefore, the number of operators should be 203 to ensure that there is sufficient capacity to meet 95% of demand.

c) Two centers are combined and let X_1 and X_2 be the number of calls at centers 1 and 2, respectively.

Then the total number of calls, X = X_1 + X_2, follows a normal distribution with

mean = 130 + 130

mean = 260, and

standard deviation = sqrt(25^2 + 25^2)

= 35.36

i) Probability that 12 operators will be able to deal with all the calls that arise in an hour can be calculated as follows:

[tex]$$\begin{aligned} \frac{X}{24} &\leq 12 \\ X &\leq 12 \times 24 \\ X &\leq 288 \end{aligned}$$[/tex]

Now, we need to find the probability of Z ≤ [tex]$$(\frac{288}{24}-260)/35.36=0.789$$[/tex].

Using normal distribution tables, we get P(Z ≤ 0.789) = 0.7852.

Hence, the probability that 12 operators will be able to deal with all the calls that arise in an hour is 0.7852.

ii) To ensure sufficient capacity to meet 95% of demand, we need to find the value of X such that: P(X ≤ x) = 0.95.

Using the Z table, we can find that the probability of Z ≤ 1.645 is 0.95.

Now, we can use the formula:

[tex]$$\frac{X}{24}-260/35.36=1.645$$[/tex]

[tex]$$X= 1.645\times 35.36\times 24+260$$[/tex]

[tex]$$X=335.58$$[/tex]

Therefore, the number of operators should be 336 to ensure that there is sufficient capacity to meet 95% of demand.

Recall that the sum of the cubic root u of 2+11i with a cubic root u of 2-11i

Now take u = 2+i and v = 2-i The indeed u³ = 2+11i, v³ = 2+11i and uv = 5

Therefore, 4(-u+v) is a root

But now take ω = -1/2 + √3/2i, Then ω² = -1/2 - √3i/2, ω = 1

u'' = ω²u, and v'' = ∈v

A blue and red dice are thrown simultaneously. Let A: the outcomes on the two dice are the same; B: the value on the red dice is greater or equal to the value on the blue dice. 4.1 Write down the sample pace for the experiment, and list events A and B in terms of set notation. 4.2 Determine P(A),P(B) and P(A|B)

Answers

P(A) = 6/36 = 1/6, P(B) = 21/36 = 7/12, P(A|B) = P(A∩B) / P(B) = 6/36 / 21/36 = 6/21 = 2/7.  The outcomes in both A and B are: {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}. The number of outcomes in A and B = 6.

4.1 Sample Space and Events in Set Notation:

When a blue and red die are thrown simultaneously, the sample space, denoted by S, consists of all possible outcomes. Since each die has six faces numbered 1 to 6, there are 36 possible outcomes in total.

Sample Space (S): {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}

Event A represents the outcomes where the values on both dice are the same:

A = {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

Event B represents the outcomes where the value on the red die is greater than or equal to the value on the blue die:

B = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,2), (2,3), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5), (3,6), (4,4), (4,5), (4,6), (5,5), (5,6), (6,6)}

4.2 Calculating Probabilities:

P(A): To find the probability of event A, we divide the number of favorable outcomes (6) by the total number of outcomes (36).

P(A) = 6/36 = 1/6

P(B): To find the probability of event B, we divide the number of favorable outcomes (21) by the total number of outcomes (36).

P(B) = 21/36 = 7/12

P(A|B): To find the conditional probability of event A given event B, we need to find the probability of A and B occurring together and divide it by the probability of event B.

The outcomes in both A and B are: {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

The number of outcomes in A and B = 6.

Write an equation of the line perpendicular to the given line that contains P.

Answers

Step-by-step explanation:

As the required line is perpendicular to y = (1/2)x + 5, product of slope of y = (1/2)x + 5 and required line should be - 1.

=> (1/2)m = - 1

=> m = - 2

Thus, required line is

=> y - (-8) = (-2)(x - 3)

=> y + 8 = -2(x - 3)
