In a recent court case it was found that during a period of 11 years 871 people were selected for grand jury duty and 37% of them were from the same ethnicity. Among the people eligible for grand jury duty, 80.7% 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 B. Ho: p= 0.807 H1: p>0.807 O A. Ho: p= 0.807 H7: p#0.807 O C. Ho: p< 0.807 H1: p= 0.807 O D. Ho: p> 0.807 H: p = 0.807 F. Ho: p = 0.807 H,: p<0.807 O E. Ho: p+0.807 H,: p= 0.807 What is the test statistic? z= (Round to two decimal places as needed.)
