A hospital claims that its emergency room has an average wait time of 2 hours (120 minutes). After a visit to their ER when we had to wait for what seemed like an eternity, we decide to test the hospital's claim because we think their claim of an average of two hours is way too low. We survey people as they exit the ER. From our sample of 58 people, we get a mean wait time of 128 minutes with a standard deviation of 23 minutes. Use alpha = 0.05.

Is the hospital's claim of two hours accurate, and why?

To promote its services, a walk-in medical clinic claims that the mean waiting time required for patients to see a doctor is 15minutes or less. To investigate this claim, a local consumer agency sent a sample of 36 “sick” people to the clinic. These people had to wait, on average, 20 minutes to see a doctor. The population standard deviation is known to be 9 minutes. Compute the value of the appropriate test statistic to test this claim. Enter your...
