Question

Two groups, A and B, consist of 100 people each who have a disease. A serum is given to group A but not to group B (which is called the control); otherwise, the two groups are treated identically. It is found that in groups A and B, 75 and 65 people, respectively, recover from the disease. What is H1? Choices: a. p1 > p2 b. p1 = p2 c. p1 < p2 d. p1 > p2

Step 1

Group A receives a serum, while Group B does not. We are given the number of people who recover in each group and are asked to identify the alternative hypothesis (H1) for a hypothesis test comparing the recovery rates of the two groups. Show more…
