In the article “Smoking and risk of myocardial infarction in women and men: longitudinal population study” published in the British Medical Journal (Prescott et al., 1998), the authors reported the results of a longitudinal study investigating the health problems associated with smoking among women. The summary data given in Table 6.14 shows the number of myocardial infarctions by smoking status for the women in this study. Use Table 6.14 to compute

(a) an estimate of the relative risk of a myocardial infarction due to the risk factor smokes.

(b) the estimated standard error of ln(ˆ????????).

(c) an approximate 95% confidence interval for the relative risk of a myocardial infarction due to the risk factor smokes.

(d) an estimate of the odds ratio for a myocardial infarction due to the risk factor smokes.

(e) the estimated standard error of ln(ˆOR).

(f) an approximate 95% confidence interval for the odds ratio for a myocardial infarction due to the risk factor smokes.
