Commuting to work: A community survey sampled 100 people in Colorado and asked them how long it took them to commute to work each day. The sample mean one-way commute time was 24.7 minutes with a standard deviation of 13 minutes. A transportation engineer claims that the mean commute time is less than 25 minutes. Do the data provide convincing evidence that the engineer's claim is true? Use the a =0.10 level of significance and the P-value method and Excel. 1
