1. Someone claims that first-year students in New Jersey public universities are as tall on average as first-year students in Pennsylvania public universities. To test that claim, you collect samples of 100 students from each of the two states and obtain the following results: The mean height for New Jersey students is 65 inches and the mean height for Pennsylvania students is 64 inches. Assume that population standard deviations are known and are 8 inches for both New Jersey and Pennsylvania. Using a significance level of 0.05, what is/are the critical value(s)?
