Thirty-five college graduates spent a mean time of 40.5 minutes commuting to work with a population variance of 67.24. Thirty workers who had completed some college had a mean commuting time of 34.8 minutes with a population variance of 39.69. At the 0.05 level of significance, can a difference in means be concluded?
