Discussion:
Solve the following problem:
Find 95% confidence intervals for the population percent dying based on these data: (1) 199 of 13,078 electronics technicians died of disease; (2) 100 of 13,078 electronics technicians died of circulatory disease; (3) 308 of 10,116 radarmen died (of any cause); (4) 441 of 13,078 electronics technicians died (of any cause); (5) 103 of 10,116 radarmen died of an accidental death.
(a) Use the normal approximation to the Poisson distribution (which is approximating a binomial distribution).
(b) Use the large-sample binomial confidence intervals . Do you think the intervals are similar to those calculated in part (a)?
