14. 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 mea weight loss for all such subjects. Does the Atkins program appear to be effective? Does i appear to be practical?
