He takes 100 patients with AIDS and gives the drug to 50 of them (group A). He gives the other 50 (group B) a placebo, sugar pill. Both groups were told that they were getting a drug that would cure their AIDS. After 6 months, 30 patients in group A reported having fewer symptoms. 10 people from group B reported having fewer symptoms. What is the hypothesis? Answer: “A scientist believes that the drug AZT will cure AIDS” 16. A scientist believes that the drug AZT will cure AIDS. He takes 100 patients with AIDS and gives the drug to 50 of them (group A).

A scientist believes that the drug AZT will cure AIDS. He takes 100 patients with AIDS and gives the drug to 50 of them (group A). He gives the other 50 (group B) a placebo, sugar pill. Both groups were told that they were getting a drug that would cure their AIDS. After 6 months, 30 patients in group A reported having fewer symptoms. 10 people from group B reported having fewer symptoms. What is the independent variable? Answer- AZT drug (Ind.Variable=experimental factor) 18. A scientist believes that the drug AZT will cure AIDS. He takes 100 patients with AIDS and gives the drug to 50 of them (group A). He gives the other 50 (group B) a placebo, sugar pill. Both groups were told that they were getting a drug that would cure their AIDS.
