Susan 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 60 Freeway. In order to determine which way she should travel on a daily basis, Susan has recorded the travel times for samples of ten trips via the 10 Freeway and ten trips via the 60 Freeway. The following table gives the travel times (in minutes) for the twenty trips. Travel times in minutes 10 Freeway 70, 70, 70, 71, 74, 65, 75, 67, 72, 66 60 Freeway 72, 74, 73, 74, 78, 75, 73, 69, 74, 70 Send data to calculator Send data to Excel 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 time via the 10 freeway, H, is different from H, the mean travel time via the 60 freeway? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis H, H, :0 H, :0 (b) Determine the type of test statistic to use. olo
