(7) Solve the problem.A manager at a bank is interested in comparing the standard deviation of the waiting times when a single waiting line isused versus when individual lines are used. He wishes to test the claim that the population standard deviation for waitingtimes when multiple lines are used is greater than the population standard deviation for waiting times when a single lineis used. This is a test of differences in variability. Find the p-value for a test of this claim given the following sample data.If you use R, you will be able to calculate a precise p-value. If you do a table lookup, you won't be able to find the exactp-value, but will be able to bound the p-value. Retain at least 4 digits in the calculated p-value if you use R.Sample 1: multiple waiting lines: n₁ = 13, S₁ = 2.0 minutesSample 2: single waiting line: n₂ = 16, s₂ = 1.1 minutes0.025 <= p-value < 0.050.01 <= p-value < 0.0250.005 <= p-value < 0.010.05 <= p-value < 0.1

For her test grades, Gena has a mean = 65 and standard deviation = 25. Patti has a mean = 65 and standard deviation = 5. For which of the students can you more accurately predict the next test score, and why? Consider the variability of scores. Who is more likely to do either extremely well or extremely poorly on the next exam, and why? Explain the reason for adjusting the formula of the standard deviation/variance with n - 1 in the denominator?
Jeremiah earned a score of 530 on Exam A that had a mean of 450 and a standard deviation of 40. He is about to take Exam B that has a mean of 63 and a standard deviation of 20. How well must Jeremiah score on Exam B in order to do equivalently well as he did on Exam A? Assume that scores on each exam are normally distributed.
The sample mean of depression scores of 16 fifth graders was 4.4 with standard deviation of 8. If the population mean of this depression score is 6, what is the calculated t score for this sample?
A researcher is interested in learning about average online hours per day for Camosun College students. Data is gathered from 50 students - mean online hours is 7.52 with a standard deviation of 2.85. Calculate the 95% CI (or alpha at 0.05) and interpret your results in a full sentence. Now calculate a 99% CI for the above. How does your answer change? If the researcher sampled a group of 24 students and the new calculated mean and standard deviation are the same as with the larger group of 50, would the 99% CI change from b above? If yes, in what way?
It has been reported that the variance of the speeds of drivers on the Turnpike near Somerset, PA is 64 for all vehicles. A driver who was pulled over near Somerset on the pike feels that value is incorrect and conducts a 4. survey of speeds. He finds that the standard deviation of 50 vehicles is 10.5 mph. At a 0.05, is the driver correct? %3D
Avalanches can be a real problem for travelers in the western United States and Canada. Slab avalanches studied in Canada had an average thickness of u = 67 cm. A sample of 31 avalanches in the U.S. gave a sample mean of = 63.0 cm. It is known that o = 10.3 cm for this type of data. Use a 0.03 level of significance to test the claim that the mean slab thickness of avalanches in the United States is different from that in Canada. Use the P-Value Approach. What is the P-Value for this problem? O 0.0154 0.0150 0.0300 0.0308
