In a recent court case it was found that during a period of 11 years 853 people were selected for grand jury duty and 36% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.5% were of this ethnicity. Use a 0.01 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. ldentify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and fina 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? CA. Ho p= 0. 785 B. H, p 0 785 H1 p= 0.785 H1: p<0.785 O C. Ho p=0.785 OD. H, p=0.785 H, p#0.785 H, p>0 785 OE H p>0.785 H: p=0.785 XE Ho p<0.785 H p=0.785 What is the test statistic? (Round to two decimal places as needed.)
