Please assist with determining the test statistic and state the P Value

12.2.21T In a randomized, placebo-controlled study, 1023 healthy women 45 years of age or older were randomly divided into two groups The women in group 1 received 100 mg of a drug every other day; the women in group 2 received a placebo every other day. The women were monitored for 10 years to determine if they experienced a cardiovascular event (such as a heart attack or stroke). of the 506 in the drug group. 10 experienced a heart attack. of the 517 women in the placebo group. 17 experienced a heart attack. Complete parts (a) through (h) below (d) What type of experimental design is this? The experiment is a completely randomized design. (e) How does randomization deal with the explanatory variables that were not controlled in the study? A. B. C. MD. (f) Determine whether the proportion of cardiovascular events in each treatment group is different using a two-sample Z-test for comparing two proportions. Use the a = 0.05 level of signicance. Randomly selecting healthy women 45 years of age or older controls for any other explanatory variables, since individuals in a larger age range might contain lurking variables, Randomly assigning the women to a group controls the amount of the drug each woman receives. Randomly assigning the women to a group controls who receive the dmg and who receives a placebo. Randomly assigning the women to a group controls for any other explanatory variables, since individuals affected by these lurking variables should be equally dispersed between the two groups, Question Help V a Let p1 represent the population proportion of women who take the drug every other day and suffer a heart atmok within 10 years and let p2 represent the population proportion of women who take the placebo every other day and suffer a heart attack within 10 years. What are the null and alternative hypotheses? A. H02p1P2 \"1:91:92 . Ho:p1=p2 H1ip1p2
