The following are hypothetical stroke mortality data from two Canadian cities, Yellowknife and Whitehorse. Yellowknife Whitehorse No. of Sex People Number of Stroke Deaths No. of Number of People Stroke Deaths Male Female 330,000 240,000 3,450 2,070 90,000 1,800 150,000 1,440 (a) Using a hand calculator, compute the crude and sex-specific risk of death from stroke in each of the two cities (b) Compute the 95% binomial exact confidence intervals of the risks computed in (a) above (c) Is it valid to use crude risk to compare the risks of death from stroke between the two cities? (d) Explain your answer in (c) above.
