A company is developing a new drug to help people lose weight. During a three month trial, 10 subjects are told to follow a diet program, an exercise program, and to take one dose of the drug each morning. Another 10 subjects are told to follow only the diet program. After the trial, 70% of the 20 test subjects reported that they had lost 10 pounds or more. Because of this, the company claimed the drug was a success. Is this claim correct?
a. No, there is no control group that just follows the diet and exercise program without the drug.
b. No, the results need to show 100% weight loss for it to be successful.
c. No, the company relied on anecdotal evidence.
d. Yes, most subjects lost weight.
