2. DETAILS MY NOTES Last year, the average wait time at the drive through at a Wendy's location was 59 seconds. This year, customers have starting talking more about things unrelated to fast food, and the manager is concerned that the mean wait time has increased. A random sample of four cars is selected and the mean wait time is calculated. For this study, use Ho: = 59 vs. Ha: > 59, where is the mean wait time. a) Suppose the sample average from those four cars was 66.90 seconds with a standard error of 4.03 seconds. Find the value of t (3 decimal places). t = b) Suppose you find a p-value of 0.072. What would you conclude at = .10? We have sufficient evidence that the mean wait time has increased. We have insufficient evidence that the mean wait time has increased. We have sufficient evidence that the mean wait time has stayed the same. We have insufficient evidence that the mean wait time has stayed the same. c) Complete the following sentence: Submit Answer This p-value of 0.072 represents the probability that, if the true wait time ---Select--- we would get a ---Select--- of at least 2.
