1. (6 points) M Daviglus et al (N Engl J Med 1997) examined the relationship of fish consumption with death from coronary heart disease (CHD) among 1,822 male employees of the Western Electric Company Hawthorne Works in Chicago who were followed for 30 years. Among 189 men who reported consumption of 0 g/day of fish at baseline, 48 died of coronary heart disease during follow-up. b. Assume the probability of death from CHD during follow-up is 48/189 = 0.2540 (measured...
