  1. A randomized controlled trial is run to evaluate the effectiveness of a new drug for asthma in children, with the outcome being relief from asthma symptoms or not (what type of variable is this?). A total of 250 children are randomized to either the new drug or placebo (125 per group). Suppose that there are 63 boys assigned to the new drug group who experience relief and 58 boys assigned to the placebo who experience relief. Is there a statistically significant difference in the proportions of boys who experienced relief? Using a 5% level of significance, your test statistic and the appropriate critical value, we should:

A.

Reject the H0

B.

None are correct

C.

Do nothing

D.

Accept the HA

E.

Do not reject the H0
