Many members of a certain workforce died from cancer supposedly resulting from exposure to radioactive fallout. Suppose that among the 215 members of the​ workforce, 88 developed cancer. For that time period and for the age of the​ cohort, the incidence of cancer was about 40​%. Use the randomization procedure and a 0.05 significance level to test the claim that the sample of this workforce is from a population in which the rate of cancer is greater than 40​%.
