Isabel 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, Isabel has recorded the travel times for samples of eight trips via the 10 Freeway and eight
trips via the 60 Freeway. The following table gives the travel timnes (in minutes) for the sixteen trips.
Travel times in minutes
10 Freeway 71, 68, 72, 72, 73, 71, 66, 76
60 Freeway 67, 75, 69, 75, 75, 81, 71, 72

Assume that the two populations of travel times are normally distributed and that the population variances are equal.
Can we conclude, at the 0.01 level of significance, that u,, the mean travel time via the 10 freeway, is different from u,, 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.)
