In a recent court case it was found that during a period of 11 years 854 people were selected for grand jury duty and 39% of them were from the same ethnicity. Among the people eligible for grand jury duty, 79.9% 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. 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? O A. Ho: p<0.799 O B. Ho: p>0.799 H₁: p=0.799 H₁: p=0.799 O C. Hop=0.799 O D. Hop=0.799 H₁: p=0.799 H₁: p > 0.799 O E. Ho: p=0.799 H₁: p<0.799 OF. Ho:p#0.799 H₁: p=0.799
