In a recent court case it was found that during a period of 11 years 857 people were selected for grand jury duty and 38% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against allowing sethnicity 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 H₁: p=0.78 O C. Ho: p=0.78 H₁: p<0.78 O E. Ho: p=0.78 H₁: p0.78 C OB. Ho: p<0.78 H₁: p=0.78 O D. Ho: p=0.78 H₁: p>0.78 OF. Ho: p *0.78 H₁: p=0.78
