The actual study found that 189 out of 2223 in the placebo group died from heart attacks and 111 out of 2221 in the treatment (Zocor) group died from heart attacks.
a. Use the Zocor study data to create a two- way table. Use Placebo and Treatment (Zocor) as the row variables. Use Death and Survival as the column variables.
b. Calculate the percentage of deaths in the placebo group and the percentage of deaths in the treatment group.
c. Calculate the difference between the two percentages calculated in Part B.
d. Calculate and interpret the relative risk of death from a heart attack.
