Participation in Clinical Trials by Race A study was conduct

Participation in Clinical Trials by Race: A study was conducted to investigate racial disparity in clinical trials of cancer. Among the randomly selected participants, 644 were white, 23 were Hispanic, 69 were black, 14 were Asian/Pacific Islander, and 2 were American Indian/Alaskan Native. The proportions of the U.S. population of the same groups are 0.757, 0.091, 0.108, 0.038, and 0.007, respectively. (Based on data from “Participation in Clinical Trials” by Murthy, Krumholz, and Gross, Journal of the American Medical Association, vol.291, No. 22.) Use a 0.05 significance level to test the claim that the participants fit the same distribution as the U.S. population. Why is it important to have proportionate representations in such clinical trials?
