Researchers investigated the issue of race and equality of access to clinical trials. The following table shows the population distribution and the numbers of participants in clinical trials involving lung cancer. Use a 0.01 significance level to test the claim that the distribution of clinical trial participants fits well with the population distribution. Is ther a race/ethnic group that appears to be very under-represented?

Race/ ethnicity	White/ Non-hispanic	Hispanic	Black	Asian/ Pacific Islander	American Indian/ Alaskan Native
Distribution of population	5.6%	9.1%	10.8%	3.8%	0.7%
Number in Lung Cancer clinical trials	3855	60	316	54	12
