Commuting to work: A community survey sampled 1923 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 24.8 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=0.01 level of significance and the critical value method with the Critical Values for the Student's t Distribution Table. Part: 0 / 5 Part 1 of 5 (a) State the appropriate null and alternate hypotheses. Ho H₁ This hypothesis test is a (Choose one) ▼ test. O
