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 25.3 minutes with a standard deviation of 13 minutes. A transportation engineer claims that the mean commute time differs from 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 P-value method with the TI-84 Plus calculator.

College tuition: The mean annual tuition and fees in the 2013-2014 academic year for a sample of 13 private colleges in California was $38,000 with a standard deviation of $7900. A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California differs from $35,0007 Use the a = 0.01 level of significance and the P-value method with the TI-84 Plus calculator.
