In a recent court case it was found that during a period of 11 years 898 people were selected for grand jury duty and 40% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.7% 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<0.787 O B. Ho: p+0.787 H:p=0.787 H: p=0.787 OC. Ho: p=0.787 O D. Ho: p>0.787 H;: p40.787 H:p-0.787 VE Ho: p=0.787 OF. Ho: p=0.787 H: p>0.787 H:p<0.787 What is the test statistic? (Round to two decimal places as needed.)

Transcribed Image Text:In a recent court case it was found that during a period of 11 years 898 people were selected for grand jury duty and 40% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.7% 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<0.787
O B. Ho: p+0.787
H:p=0.787
H,: p=0.787
OC. Ho: p=0.787
O D. Ho: p>0.787
H: p40.787
H:p-0.787
VE Ho: p=0.787
OF Ho: p=0.787
H: p>0.787
H:p<0.787
What is the test statistic?
z-O
(Round to two decimal places as needed.)
