Please follow the steps in testing hypothesis A diet clinic states that there is an average loss of 24 pounds for those who on the program for 20 weeks. The standard deviation is 5 pounds. The clinic tries a new diet, reducing salt intake to see whether that strategy will produce a greater weight loss. A group of 40 volunteer loses an average of 16.3 pounds each over 20 weeks. Should the clinic change the new diet? Test at α = 0.
