    Researchers investigated the issue of race and equality of access to clinical trials. The table below shows the population distribution and the numbers of participants in clinical trials involving lung cancer (Based on data from "Participation in Cancer Clinical Trials," by Murthy, Krumholz, and Gross, Journal of the American Medical Association, Vol. 291, No. 22).

    Use a 0.01 significance level to test the claim that the distribution of clinical trial participants fits well with the population distribution.

    Race/ethnicity White Non-Hispanic Hispanic Black Asian
    Pacific Islander. American Indian
    Alaskan Native
    Distribution of Population 75.6% 9.1% 10.8% 3.8% 0.7%
    # in L.C. clinical Trials 3855 30 316 54 12

    Is there race/ethic group that appears to be very underrepresented based on the results?
