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 va 60 Freeway. In ordev to determine which way she should travel on a daily basis, Amy has recorded the travel times for samples of nine trips via the 10 Freeway and nine trips via the 60 Freeway. The following table gives the travel times (in minutes) for the eighteen trips: Travel times in minutes 10 Freeway 68, 68, 69, 67, 72, 71, 75, 73, 70 60 Freeway 82, 81, 73, 69, 71, 66, 71, 72, 72 Assume that the two populations of travel times are normally distributed and that the population variances are equal. Can we conclude, at the 0.05 level of significance, that the mean travel times of the two routes are different? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
