Texas Health Harris Methodist measures the average wait time for patients in the ER as 45 minutes. The average wait time for the ER is normally distributed. The hospital decided to check if this is still true, the quality control staff recorded 45 observations of the wait time of ER patients. Using the observations below, is there evidence that the average wait time for ER patients is not 45 minutes? Use a level of significance of .05

1. Copy the data into excel and do an analysis to test the hypothesis

2. What is the conclusion of your analysis? (try to state it in terms of the original problem or question)
