A cohort study evaluating causes of mortality among 20,000 men (aged 40-59) with coronary heart disease was conducted, following men for 2 years. If were smokers at the time of enrollment, they were told of the continued health risks associated with smoking. The number of deaths occurring by the end of the 2-year period among men classified by smoking behavior are given below. Fill in the mortality rate for each group. Smoker at baseline and continued smoking through study Smoker...

Suppose that 5 men in 100 are colorblind, while 24 women in 10,000 are colorblind. Compute the probability that a colorblind individual is male. Assume that the population contains an equal number of males and females. Round your answer to two decimal places. (If necessary, consult a list of formulas.)

A large study showed that aspirin reduced the rate of first heart attacks. A pharmaceutical company thinks that they have a drug that will be more effective than aspirin, and plans to do a randomized clinical trial to test the new drug. They determine the following null and alternative hypotheses: Example 2: a) Ho: the new drug is not more effective than aspirin HA: the new drug is more effective than aspirin hey conduct the trial. The group that used...
