cument, click Duplicate. 18 2. (t Test (in Excel) for Two Samples with Equal Variances) Amy has two ways to travel from her home in Norco to her office in Los Angeles. One is to go via the 10 Freeway, and the other is to go via the 60 Freeway. In order to determine which way she should travel on a daily basis, Amy has recorded the travel times for samples of fifteen trips via the 10 Freeway and fifteen trips via the 60 Freeway. The following table gives the travel times (in minutes) for the thirty trips: 10 Freeway 60 Freeway Travel times in minutes 74, 68, 75, 73, 73, 73, 69, 72, 70, 77, 67, 71, 74, 71, 71 Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.075 level of significance, that the mean travel time via the 10 Freeway is less than the mean travel time via the 60 Freeway?
