In a recent court case it was found that during a period of 11 years 884 people were selected for grand jury duty and 35% 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. Which of the following is the hypothesis test to be conducted? A. H0: p=0.799 H1: p>0.799 B. H0: p=0.799 H1: p<0.799 C. H0: p>0.799 H1: p=0.799 D. H0: p=0.799 H1: p≠0.799 E. H0: p≠0.799 H1: p=0.799 F. H0: p<0.799 H1: p=0.799 What is the test statistic? z= (Round to two decimal places as needed.) What is the P-value? P-value= (Round to four decimal places as needed.)
