#7 In a recent court case it was found that during a period of 11 years 885 people were selected for grand jury duty and 38% of them were from the same ethnicity. Among the people eligible for grand jury duty, 79.9% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. What is the test statistic? Determine the P-value Use the results of the hypothesis test to conclude whether evidence exists to support the original claim that the selection process is biased against allowing this ethnicity to sit on the grand jury.
