3. In a test of weight loss programs, 40 adults used the Atkins weight loss program. After 12 months, their mean weight loss was found to be 2.1 lb, with a standard deviation of 4.8 lb. Construct a 90% confidence interval estimate of the standard deviation of the weight loss for all such subjects. Does the confidence interval give us information about the effectiveness of the diet?

Atkins Weight Loss Program: In a test of weight loss programs, 40 adults used the Atkins weight loss program. After 12 months, their mean weight loss was found to be 2.1 lb, with a standard deviation of 4.8 lb. Construct a 90% confidence interval estimate of the mean weight loss for all such subjects. Does the Atkins program appear to be effective? Does it appear to be practical? Can this be constructed in XLSTAT? Where would you find the data...

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.

A study was conducted to determine the effectiveness of a diet program in reducing weight of obeys people. Eight randomly selected patients were put on this diet and the amount of weight losses (in pounds) were recorded. Suppose the sample mean and the sample standard deviation of weight losses were 38 and 4.598136 pounds, respectively. Construct a 90% confidence interval for the average weight loss and based on the confidence interval constructed determine if you would expect to see an...
