In a recent court case it was found that during a period of 11 years 865 people were selected for grand jury duty and 40% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.9% 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? A. Ho: p=0.789 H₁: p<0.789 OC. Ho: p>0.789 H₁: p=0.789 O E. Ho: p=0.789 H₁: p 0.789 What is the test statistic? Z= (Round to two decimal places as needed.) OB. Ho: p<0.789 H₁: p=0.789 OD. Ho: p 0.789 H₁: p=0.789 OF. Ho: p=0.789 H₁: p>0.789

In a recent court case it was found that during a period of 11 years 865 people were selected for grand jury duty and 40% of them were from the same ethnicity. Among the people eligible for grand
jury duty, 78.9% 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?
A. Ho: p=0.789
H₁: p<0.789
OC. Ho: p>0.789
H₁: p=0.789
O E. Ho: p=0.789
H₁: p 0.789
What is the test statistic?
Z=
(Round to two decimal places as needed.)
OB. Ho: p<0.789
H₁: p=0.789
OD. Ho: p 0.789
H₁: p=0.789
OF. Ho: p=0.789
H₁: p>0.789
