The Bureau of the Census reports that the average commuting time for citizens of both Baltimore, Maryland, and Miami, Florida is approximately 29 minutes (uMiami=29 and uBaltimore=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 provided below. At the 0.05 level of significance, can it be concluded times are different in the winter? Miami Baltimore Sample size 40 40 Sample mean 28.5 mins 35.2 mins Population Standard deviation 7.2 mins 9.1 mins.
