In a recent court case it was found that during a period of 11 years 852 people were selected for grand jury duty and 37% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78% 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? ОА. Но: р> 0.78 H4:p= 0.78 в. Но: р 0.78 H1:p<0.78 O C. Họ: p#0.78 H4:p= 0.78 O D. Ho: p= 0.78 H4:p>0.78 O E. Ho: p<0.78 OF. Ho: p=0.78 H4:p=0.78 H4:p+0.78 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 852 people were selected for grand jury duty and 37% of them were from the same ethnicity. Among
the people eligible for grand jury duty, 78% 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>0.78
H4: p= 0.78
OB. Ho: p= 0.78
H1: p<0.78
OC. Ho: p+0.78
O D. Ho: p= 0.78
H1: p= 0.78
H1: p>0.78
O E. Ho: p<0.78
O F. Ho: p= 0.78
H4: p= 0.78
H1: p#0.78
What is the test statistic?
(Round to two decimal places as needed.)
