Question: A sample of ten ER patients was conducted to determine their average wait tiMeand to compare this to the target wait time. The hospital wants to make sure that patients do not wait more than 35 minutes. Test the following hypotheses using a 95% confidence level.

H_O: wait time is less than or equal to 35 minutes

Ha: wait time is greater than 35 minutes

A. What is the mean waiting time?

B. What is the standard deviation for waiting times?

C. What is your test statistic, t?

D. What is the threshold that must be exceeded to reject H₀?

E. What is the two tailed probability that you would observe this amount of difference between the sample mean and the hypothesized value?

F. What is the one tailed probability that you would observe this amount of difference between the sample mean and the hypothesized value?
