As per the impact of reducing the tolerable rate of deviation from 7% to 5% on the sample size is 93.

The term deviation is defined as a measure that is used to find the difference between the observed value and the expected value of a variable.

Here we have given that the audit team is planning to examine a sample of control policies and procedures. assume that, based on the intended degree of reliance on internal control, the audit team wishes to control the risk of overreliance to 5%.

And we need to find sample size.

While we looking into the given question, we know that the tolerable rate of deviation from 7% to 5% on the sample size.

Let us consider that 100 be the sample size, then the reduction in 7% to 5%, tell that there is an 2% decrement in the sample size.

Therefore, it can be calculated as,

=> 100 x 2/100

=> 2

Here we already know that the risk of overreliance to 5%.

Then the total value is

=> 5 + 2 = 7.

Then the sample size is

=> 100 - 7

=> 93.

The probability for all sample of 5 that the sample mean will be greater than 22 pounds is approximately 0.05.

The distribution of backpack with mean deviation = 19.7 pounds

And the standard deviation = 3.1 pounds

According to this question,

He normal probability distribution and the central limit theorem were used.

Normal probability distribution, ; Problems of normally distributed samples are solved using the z-score formula.

Mean standard deviation, the z-score of a measure X is given by:

Z = x-μ/σ

The Z-score measures how many standard deviations. the measure is from the mean.

After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score.

This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.

Subtracting 1 by the p value,

We get the value probability that of the measure is greater than X.

Central Limit Theorem;  The Central Limit Theorem establishes  that, for a normally distributed random variable X, with mean  and standard deviation the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For samples of size 5, which of the following is the best interpretation of P(ä > 22) = 0.05

No matter the size of the sample mean will be the same.

However, the standard deviation will be changed.

P(ä > 22) is the probability of the sample means being above 22.

For all samples of size 5, the probability that the sample mean will be greater than 22 pounds is approximately 0.05.

Answer:

The number of downloads of the standard version is 230.

Step-by-step explanation:

Let x be the number of downloads of the standard version.

The number of downloads of the high-quality version is 4x.

The total size downloaded for the standard version is 2.8x MB.

The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.

The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.

Combining like terms, we have 20x = 4600 MB.

Dividing both sides by 20, we have x = 230 downloads of the standard version

However, the information is not complete but we can see parallel lines in general to solve it.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other.

Perpendicular lines are those that cross at a straight angle of 90 degrees.

Lines that are perpendicular to one another are those that are 90 degrees apart. In light of this definition, we could conclude that for lines lll and mmm to be perpendicular, they must intersect and form a right angle (90°) to one another.

The probability the card is red, given that it is a face card is 1/2 and  the probability the card is a king, given that it is a face card is 1/3.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

A card is drawn from a standard 52-card deck (no jokers).

We have to match each event with its probability.

Since, a deck of cards contains the face cards J, Q, and K.

Let's say there are four different kinds of cards: spades, clubs, hearts, and diamonds.

King, Queen, and Jack are contained in each of these types.

Thus, the total number of face cards is 12 (3 x 4).

(1)  Let the face cards are 12 and there are 6 red cards in that 12 face cards.

So, the probability the card is red, given that it is a face card is

= 6/12 = 1/2.

(2)  There are 4 king in a 12 face cards.

So, the probability the card is a king, given that it is a face card

= 4/12 = 1/3.

Hence the probability the card is red, given that it is a face card is 1/2 and  the probability the card is a king, given that it is a face card is 1/3.

Thus, Marsha earn $1350.

Step-by-step explanation:

Let the larger angle be x.

Smaller angle = x - 8

As both angles are supplementary,

x + (x - 8) = 180°

Micah's best long jump is 3 meters long.

In this question we have been given Avi and Micah are teammates on a track and field team.

We need to find the how long is Micah's best long jump.

Let Micah's best long jump is x meters and Avi's  best long jump is y meters.

Avi's best long jump is 3 1/2 meters.

⇒ y = 3 1/2 meters

We write this improper fraction as proper fraction.

3 1/2 = 7/2

Also, Avi's best long jump is 1 1/6 times as long as Micah's.

So, we get an equation

y = (1 1/6) * x

We write improper fraction 1 1/6 as 7/6

So equation becomes,

y = 7/6 * x

Subatitute the value of y

7/2 = 7/6  * x

x = (7/2)/(7/6)

x = 6/2

x = 3 meters

At least 75% of his total credits were certain to have a grade point average between 2.00 and 4.0.

By looking at the standard deviation of 0.25, we can calculate the range of the grade point averages which are within two standard deviations away from the mean. In this case, the mean is 3.00, so two standard deviations away would be 2.00 (3.00 - 0.25 x 2) and 4.00 (3.00 + 0.25 x 2). Since the grade point averages within this range are certain to have a grade point average between 2.00 and 4.0, at least 75% of the total credits are certain to have a grade point average between these two numbers.

Lower limit (2 standard deviations away from the mean):

3.00 - (0.25 x 2) = 2.00

Upper limit (2 standard deviations away from the mean):

3.00 + (0.25 x 2) = 4.00

Therefore, at least 75% of the total credits have a grade point average between 2.00 and 4.00.

The correct answer is a. margin of error.

The margin of error is a measure of the precision of a survey or poll. It represents the range of values within which the true value of the population parameter being measured is likely to fall, based on the sample data collected. A smaller margin of error indicates a higher level of precision and a more reliable estimate of the population parameter. In general, a margin of error of less than +/- 5 is considered to be a good benchmark for a reliable public opinion poll.

The modal response is the most common response to a survey question. The sample size is the number of people included in the survey. Standard deviation is a measure of the dispersion of a set of data. Self-selection bias refers to the possibility that the people who choose to participate in a survey are not representative of the entire population being studied.

According to the information given in the question,

The coordinates of the vertices of the park are,

( 1, 1 ), ( 1, 4 ), and ( -3, 4 )

We have to find the coordinates of the recycle bin.

Let us consider the equation of the circle,

[tex]x^{2} +y^{2}+Dx + Ey+ F =0[/tex]

So putting the values of the coordinates into the equation,

First Equation,

[tex]1^{2}+1^{2} + D + E + F = 0[/tex]

Second Equation,

[tex]1^{2} +4^{2} +D + 4E + F=0[/tex]

Third Equation,

[tex](-3)^{2} + 4^{2} - 3D+4E+F=0[/tex]

Subtracting the first equation from the second,

[tex]1^{2} +4^{2} +D + 4E -E=0[/tex]

15 + 3E = 0

3E = -15

E = -5

Subtracting the third equation from the second,

1 + 16 - 9 - 16 + D + 3D = 0

4D = 8

D = 2

Putting the values of E and D in the first equation,

1 + 1 + D + E + F = 0

F = -2 - D - E

F = 1

So now the equation of the circle becomes,

[tex]x^{2} +y^{2}+2x - 5y+ 1 =0[/tex]

By expanding the above equation we can find the standard equation,

[tex]x+2x+1^{2} +y^{2} -5y+ 2.5^{2}- 1^{2} -2.5^{2} +1 =0[/tex]

[tex](x+1)^{2} + (y - 2.5)^{2} = 1^{2} + 2.5^{2} -1[/tex]

[tex](x+1)^{2} + (y - 2.5)^{2} = 2.5^{2}[/tex]

So the required circumcenter will be = ( -1, 2.5 )
