Question

Jean lives about 10 miles from the college where she plans to attend a 10-week summer class. There are two main routes she can take to the school, one through the city and one through the countryside. The city route is shorter in miles, but has more stoplights. The country route is longer in miles, but has only a few stop signs and stoplights. Jean sets up a randomized experiment where each day she tosses a coin to decide which route to take that day. She records the following data for 5 days of travel on each route. Country Route - 17, 15, 17, 16, 18 City Route - 18, 13, 20, 10, 16 It is important to Jean to arrive on time for her classes, but she does not want to arrive too early because that would increase her parking fees. Based on the data gathered, which route would you advise her to choose?

a. The Country Route, because the times are consistently between 15 and 18 minutes.

b. The City Route, because she can get there in 10 minutes on a good day and the average time is less than for the Country Route.

c. Because the times on the two routes have so much overlap, neither route is better than the other. She might as well flip a coin.
