The administrator at your local hospital states that on weekends the average wait time for emergency room visits is 12 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 administrator's claim. You decide to test your hypothesis. Over the course of a few weekends you record the wait time for 50 randomly selected patients. The average wait time for these 50 patients is 15 minutes. The population standard deviation is 3 minutes. Do you have enough evidence to support your hypothesis that the average ER wait time is more than 12 minutes? You opt to conduct the test at a 5% level of significance. Which of the following hypothesis testing procedure fits the given problem?
