The CEO of a popular company claims that the mean response time for customer service calls is 9 minutes.A group of recent customers believes that the mean response time is actually slower than that, meaning ittakes more than 9 minutes. The customers wish to conduct a hypothesis test at the a = 0.05 level ofsignificance to determine if their claim that it is slower is correct.Which would be correct hypotheses for such a test?Ho:u = 9, Hị: µ > 9Ho:4 + 9, Hị: µ = 9%3DOHo:H < 9, Hị :H = 9ΘΗ :μ = 9, Η :μ <9ΘΗ:μ = 9, Η :μέ9What does the P-value measure?O The power of mind of the statistician who performed the statistical experimentO The probability that the alternate hypothesis is trueThe probability that the results of a statistical experiment are due only to chanceO The probability that the results of an statistical experiment are due to something more significantthan chanceIf the resulting P-value is 0.065, which would be the appropriate conclusion?There is significant evidence to suggest that the actual mean response time is more than 9O There is significant evidence to suggest that the actual mean response time is less than 9There is not significant evidence to suggest that the actual mean response time is less than 9There is not significant evidence to suggest that the actual mean response time is more than 9

Claim: The mean response time is actually slower than that i.e more than 9 minutes.

I looked at the answer for the question 8.22,but I have no idea why alpha is equal to 0.05 and how do we get the formula and how do we know it is t distribution.By the way,could you use R code to calculate this value?
The null hypothesis for a repeated-measures test states O cach individual will have a difference score of D-0 the overall sample will have a mean difference of Mo -0 O the entire population will have a mean difference of do -0 O Allof the other options are correct

7:39 Done A myopenmath.com AA Lindsey and Andrea began arguing about who did better their tests, but they couldn't decide who did better given that they took different tests. Lindsey took a test in Social Studies and earned a 75.2, and Andrea took a test in Math and earned a 68.1. Use the fact that all the students' test grades in the Social Studies class had a mean of 73.7 and a standard deviation of 11.4, and all the students' test grades in Math had a mean of 60.4 and a standard deviation of 10.8 to answer the following questions. a) Calculate the z-score for Lindsey's test grade. = Z b) Calculate the z-score for Andrea's test grade. c) Which person did relatively better?
