1. 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 about how long they waited to be seen in the ER over a weekend, you dispute the administrator's claim. You decide to test your hypothesis. Over the course of a few weekends, you record the wait time for 40 randomly selected patients, below. Is there enough evidence in the collected data to support your hypothesis that the average ER wait time exceeds 10 minutes? 
2. You opt to conduct the test at a 5% level of significance.
   Wait time (in minutes): 10.3, 17.6, 10.4, 7.1, 6.2, 7.8, 13.0, 9.8, 10.5, 10.2, 10.3, 11.0, 14.1, 12.0, 10.4, 9.3, 10.5, 6.0, 7.5, 16.7, 12.0, 13.6, 6.2, 9.5, 12.1, 5.7, 10.8, 12.6, 12.6, 10.7, 7.9, 5.4, 10.1, 11.0, 13.0, 10.6, 11.1, 11.7, 13.3, 10.8
