In a recent court case it was found that during a period of 11 years 872 people were selected for grand jury duty and 36% of them were from the same ethnicity. Among the people eligible for grand jury duty, 80.9% 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? OA. Ho: p=0.809 OB. Ho: p>0.809 H₁: p>0.809 H₁: p=0.809 OC. Ho: P 0.809 OD. Ho: p=0.809 H₁: p=0.809 H₁: p=0.809 OE. Ho: p<0.809 H₁: p=0.809 F. Ho: p=0.809 H₁: p<0.809 What is the test statistic? Z= (Round to two decimal places as needed.) O >
