In a recent court case it was found that during a period of 11 years 850 people were selected for grand jury duty and 39% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.3% 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<0.783 H₁: p=0.783 C. Ho: p=0.783 H₁: p<0.783 OE. Ho p=0.783 H₁: p 0.783 What is the test statistic? z= (Round to two decimal places as needed.) OB. Ho: p>0.783 H₁: p=0.783 OD. Ho: p=0.783 H₁: p>0.783 OF. Ho: p 0.783 H₁: p=0.783

In a recent court case it was found that during a period of 11 years 850 people were selected for grand jury duty and 39% of them were from the same ethnicity. Among the people eligible for grand
jury duty, 78.3% 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<0.783
H₁: p=0.783
C. Ho: p=0.783
H₁: p<0.783
OE. Ho p=0.783
H₁: p 0.783
What is the test statistic?
z=
(Round to two decimal places as needed.)
OB. Ho: p>0.783
H₁: p=0.783
OD. Ho: p=0.783
H₁: p>0.783
OF. Ho: p 0.783
H₁: p=0.783
