A sports news station wanted to know whether people who live in the North or the South are bigger sports fans. For its study, 151 randomly selected Southerners were surveyed and found to watch a mean of 4.6 hours of sports per week. In the North, 159 randomly selected people were surveyed and found to watch a mean of 3.5 hours of sports per week. Find a 95% confidence interval for the true difference between the mean numbers of hours of sports watched per week for the two regions if the South has a population standard deviation of 1.2 hours per week and the North has a population standard deviation of 1.8 hours per week. Let Population 1 be people who live in the South and Population 2 be people who live in the North. Round the endpoints of the interval to one decimal place, if necessary.
