4. As part of a study of corporate employees, the director of human resources for PNC Inc. wants to compare the distance traveled to work by employees at its office in downtown Cincinnati  with  the  distance  for  those  in  downtown  Pittsburgh.  A  sample of 35 Cincinnati employees showed they travel a mean of 370 miles  per  month.  A sample of 40 Pittsburgh employees showed they travel a mean of  380  miles per month. The population standard deviation for the Cincinnati and Pittsburgh employees are 30 and 26 miles, respectively. At the .05 significance level, is there a difference in the mean number of miles traveled per month between Cincinnati and Pittsburgh employees?
