Assume that when human resource managers are randomly selected, 49% say job applicants should follow up within two weeks. If 7 human resource managers are randomly selected, find the probability that exactly 2 of them say job applicants should follow up within two weeks.
The probability that exactly 2 of them say job applicants should follow up within two weeks is 33.02%.
How to find the probability ?We can use the binomial probability formula:
P(x) = C ( n, x ) × p ^ x × ( 1 - p ) ^ ( n - x )
Solving then gives:
P ( 2 ) = C ( 7, 2 ) x 0.49 ^ 2 x ( 1 - 0. 49 ) ^ ( 7 - 2)
P ( 2 ) = 21 x 0. 49 ^ 2 x ( 1 - 0. 49) ^5
= 21 x 0. 2401 x 0. 078109
= 0. 3302
In conclusion, the probability that 2 of the 7 human resource managers say job applicants should follow up within two weeks is approximately 0.3302 or 33.02%.

Americans are stressed out!
A psychologist would like to estimate the proportion of Americans that say "the future of the nation is a
significant source of stress for me." To help form an estimate, the psychologist randomly selected 664
Americans and found that 69.6% of the sample agreed with the statement "the future of the nation is a
significant source of stress for me."
Using a 99% confidence level, determine the margin of error, E, and a confidence interval for the true
proportion of all Americans that say the "the future of the nation is a significant source of stress for me."
Report the confidence interval using interval notation. Round solutions to four decimal places, if necessary.
The margin of error is given by E:
A 99% confidence interval is given by:
To find the margin of error, we can use the formula: E = z√((p(1-p))/n)
How is margin of error determined?where z is the z-score for a 99% confidence level, p is the sample proportion, and n is the sample size.
From the table of standard normal distribution, the z-score for a 99% confidence level is 2.576.
Plugging in the values, we get:
E = 2.576√((0.696(1-0.696))/664) ≈ 0.0385
So the margin of error is 0.0385.
To find the confidence interval, we can use the formula:
p ± E
where p is the sample proportion and E is the margin of error.
Plugging in the values, we get:
0.696 ± 0.0385
So the 99% confidence interval for the true proportion of all Americans that say "the future of the nation is a significant source of stress for me" is (0.6575, 0.7345). In interval notation, this can be written as [0.6575, 0.7345].

Sarah has a coupon for an oil change with synthetic oil for $49.95. She can buy 5 quarts of synthetic oil, which is what her car needs, for $37.54 and an oil filter for $9.47. How much can she save by doing the oil change herself?
Step-by-step explanation:
If Sarah buys the oil and oil filter separately, she would spend:
Cost of oil = $37.54
Cost of oil filter = $9.47
Total cost = $37.54 + $9.47 = $47.01
Therefore, Sarah can save:
Coupon price - Total cost = $49.95 - $47.01 = $2.94
So, Sarah can save $2.94 by doing the oil change herself instead of using the coupon.
Scott and Lana booked a cruise that departs from Seward, Alaska, but their flight flew into Anchorage, Alaska. The couple decided to travel from Anchorage to Seward on the Alaska Railroad's non-stop Coastal Classic route to enjoy the 117 miles of beautiful scenery. If the train had traveled 13 miles in 30 minutes, how long, in hours, was the non-stop train ride from Anchorage to Seward?
A. 4.5 hours
B. 18 hours
C. 3 hours
D. 9 hours
The answer is option A. That is, the time taken in hours if the train traveled 13 miles in 30 minutes is 4.5 hours.
What is the relation between distance travelled and time?The relation between distance traveled and time is given by the formula:
Distance = Speed x Time
where distance is the total distance traveled, speed is the rate at which the distance is covered, and time is the duration for which the distance is covered. This formula applies to any type of motion, whether it is linear or circular, and it is often used to calculate the distance covered by an object given its speed and the time it traveled. Alternatively, the formula can also be used to calculate the time required to travel a certain distance given the speed at which the object is traveling.
Given that the total distance = 117 miles. We need to find the time taken in hours if the train traveled 13 miles in 30 minutes.
For that we can use the equation, distance = rate x time
Now, rate = distance/time
Distance = 13 miles, time = 30 minutes = 30/60 hours = 0.5 hours
Therefore, rate = 13 miles / 0.5 hours = 26 miles per hour
Now to find the time it took to travel the entire 117 miles:
time = distance/rate
time = 117 miles/ 26 miles per hour
time = 4.5 hours
Therefore, the answer is (A) 4.5 hours.

The mean weight of an adult is 70 kilograms with a standard deviation of 8 kilograms.
If 87 adults are randomly selected, what is the probability that the sample mean would be greater than 70.8 kilograms? Round your answer to four decimal places.
The probability that the sample mean would be greater than 70.8 kilograms is given as follows:
0.1762 = 17.62%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by the equation presented as follows: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 70, \sigma = 8, n = 87, s = \frac{8}{\sqrt{87}} = 0.8577[/tex]
The probability is one subtracted by the p-value of Z when X = 70.8, hence:
Z = (70.8 - 70)/0.8577
Z = 0.93
Z = 0.93 has a p-value of 0.8238

using cramer rao lower bound method, with a random sample of size n, find a minimum variance unbiased estimator of the parameter,λ of a poisson population
The minimum variance unbiased estimator of the parameter,λ of a poisson population is λ = Σxi/n.
What is variance?Variance is a measure of how spread out a set of data is. In statistics, it is the average of the squared differences from the mean of a set of values. It is calculated by taking the sum of the squared deviations from the mean and dividing it by the number of data points.
According to given information:Let X1, X2, ..., Xn be a random sample from a Poisson distribution with mean λ. The likelihood function is given by:
[tex]L(\lambda | x) = \pi[e^{(-\lambda)} \lambda^{(xi)} / xi!][/tex]
Taking the natural logarithm and differentiating with respect to λ:
ln L(λ | x) = -nλ + ln(λ) Σxi - Σln(xi!)
d/dλ ln L(λ | x) = -n + Σxi/λ
Setting the derivative equal to zero and solving for λ, we get:
λ = Σxi/n
This is the sample mean of the Poisson distribution, which is an unbiased estimator of λ. Moreover, using the Cramer-Rao lower bound, we can show that it is also the minimum variance unbiased estimator of λ.

The other angle that is congruent to ∠DFA is: ∠BFC
How to identify Congruent angles?Congruent angles are defined as two or more angles that are said to be identical to each other. This means that the measure of these angles is equal to each other. These type of angles do not make any difference in the congruence of angles, which tells us that they can be acute, obtuse, exterior, or interior angles.
Now, we want to find the angle that is congruent to ∠DFA.
By inspection, we can see that ∠BFC is an opposite angle to ∠DFA.
We know that Opposite angles are the two angles opposite each other when two lines cross. They can also be called vertical angles due to sharing a vertex, which is the point where the two lines connect. Opposite angles always have the same measurement, making them congruent.

The distance for boat is,
= 43.2 miles
Given that;
Edward and Diana walked to the dock at 2 miles per hour, jumped into the boat, and motored to Dillion at 10 miles per hour
Now, For Walk DATA:
Rate = 2 mph ; time = x hrs.
Then, distance = 2x miles
For Boat DATA:
Rate = 10 mph ; time = 5 - x hrs
Then, distance = 10 (5 - x) miles
Hence, We can formulate;
distance + distance = 12 miles
2x + 10 (5 - x) = 20
2x + 50 - 10x = 20
30 = 8x
x = 3.6
Hence, Boat time ,
