A group of 78 people enrolled in a weight-loss program. They also had to adhere to a regular exercise program. After six months, the mean weight loss was 25 pounds with a standard deviation of 9 pounds. A second group of 43 people enrolled in the same program with the exception of regular exercise. After six months, their mean weight loss was 14 with standard deviation 7 pounds. Construct a 99% confidence interval for the mean difference in weight losses.
