# Question: According to the U S Census Bureau the average travel time

According to the U.S. Census Bureau, the average travel time to work in Philadelphia is 27.4 minutes. Suppose a business researcher wants to estimate the average travel time to work in Cleveland using a 95% level of confidence. A random sample of 45 Cleveland commuters is taken and the travel time to work is obtained from each.

The data follow. Assuming a population standard deviation of 5.124, compute a 95% confidence interval on the data. What is the point estimate and what is the error of the interval? Explain what these results means in terms of Philadelphiacommuters.
