A sample of 29 body temperatures resulted in a mean of 98.3o and a standard deviation of .24o. Use these sample statistics to construct a 98% confidence interval estimate of the standard deviation of body temperature of all healthy humans. In a test of the Atkins weight loss program, 65 individuals participated in a randomized trial with overweight adults. After 12 months, the mean weight loss was found to be 5.1 lb, with a standard deviation of 4.8 lb. construct...
