Reference no: EM131115664

The administrator at your local hospital states that on weekends the average wait time for emergency room visits is 10 minutes.  Based on discussions you have had with friends who have complained on how long they waited to be seein in the ER over a weekend, you dispute the administrator's claim. You decide to test you hypothesis. Over the course of a few weekends you record the wait time for 40 randomly selected patients. The average wait time for these 40 patients is 11 minutes with a standard deviation of 3 minutes. Do you have enough evidence to support your hypothesis that the average ER wait time exceeds 10 minutes? You opt to conduct the test at a 5% level of significance.
