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 seen in the ER over a weekend, you dispute the administrators claim. 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 as 11 minutes with a standard deviation of three 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. a) are condition sufficiently met to perform a task? Why or why not? b) what type of test should we use? c) write a hypothesis and specify the type of test (tailing). Use the appropriate notation for the hypothesis.
