proportions of smokers

Smoking. In the depression and heart attack research described in Exercise 13, 32% of the diseased group were smokers, compared with only 23.7% of those free of heart disease.

a) Create a 95% confidence interval for the difference in the proportions of smokers in the two groups.

b) Is this evidence that the two groups in the study were different? Explain.

c) Could this be a problem in analyzing the results of the study? Explain.

Exercise 13:

Age. In a study of how depression may affect one s ability to survive a heart attack, the researchers reported the ages of the two groups they examined. The mean age of 2397 patients without cardiac disease was 69.8 years  while for the 450 patients with cardiac disease, the mean and standard deviation of the ages were 74.0 and 7.9, respectively.

a) Create a 95% confidence interval for the difference in mean ages of the two groups.

b) How might an age difference confound these research findings about the relationship between depression and ability to survive a heart attack?
