A train station is interested in calculating the average wait time for passengers to wait for their trains arrival. The station hired a data analyst who took a random sample of 60 random passengers. The analyst discovered that the sample mean was 90 minutes, and the population standard deviation was 10 minutes.

A study conducted by a commuter train transportation authority involved surveying a random sample of 200 passengers. The results show that a customer had to wait on the average 9.3 minutes with a standard deviation of 6.2 minutes to buy his or her ticket. Find the margin of error for estimating the population mean waiting time.

A study conducted by a train transportation authority with a random sample of 300 passengers shows that a passenger had to wait on the average 9.3 minutes to buy their ticket. The transportation authority is interested in whether it is reasonable to conclude that the mean wait time is less than 10.3 minutes. Use a population standard deviation of 6.2 minutes and the 0.05 significance level. what is the p-value of the sample data?
