Question

g) determine the point estimate of the population mean 

h) determine the margin of error for the 96% confidence interval 

i) specify the confidence interval 
g) give a brief interpretation of the confidence interval as related to ER wait times at the local hostpital 

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 administrator's 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 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.
