A sample 36 obese adults was put on a special low carbohydrate diet for a year. The average weight loss was 11 lb and the standard deviation was 19 lb (note that, positive weight loss imply reduced weight over the time).

- Calculate the 99% confidence interval for the true mean weight reduction (Do the calculations by hand).

- Obtain the interval using MINITAB (attach the output)

- Based on the above confidence interval do you have sufficient evidence to believe that this diet program in fact helps reduce weight? Explain.
