8. Commuting Times The U.S. Census Bureau reports that the average commuting time for citizens of both Baltimore, Maryland, and
Miami, Florida, is approximately 29 minutes. To see if their commuting times appear to be any different in the winter, random
samples of 40 drivers were surveyed in each city and the average commuting time for the month of January was calculated for both
cities. The results are shown. At the 0.05 level of significance, can it be concluded that the commuting times are different in the
winter?
