Does anyone have the answers to Chemistry semester B end of course exam answers

1. 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?

Therefore, the claim cannot be fully supported without further evidence.
