In a recent court case it was found that during a perio 11 years 891 people were selec grand jury duty and 38% them were from the same ethnicity. Among the people eligible for grand jury duty, 78.4% 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, 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 t the binomial distribution. Which of the following is the hypothesis test to be conducted? OA. Ho: p*0.784 H₁: p=0.784 OC. Ho: p=0.784 H₁: p>0.784 OE. Ho: p<0.784 H₁: p=0.784 What is the test statistic? 2=0 (Round to two decimal places as needed.) What is the P-value? P-value= (Round to four decimal places as needed.) OB. Ho: p=0.784 H₁: p*0.784 O D. Ho: p=0.784 H₁: p<0.784 OF. Ho: p>0.784 H₁: p=0.784

Question
In a recent court case t was found that during a period of 11 years 891 people were selected for grand jury duty and 38% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.4% 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? O A. Ho: p0.784 H₁: p= 0.784 OC. Ho: p=0.784 H₁: p>0.784 O E. Ho: p<0.784 H₁: p=0.784 What is the test statistic? z= (Round to two decimal places as needed.) What is the P-value? P-value= (Round to four decimal places as needed.) C O B. Ho: p=0.784 H₁: p0.784 O D. Ho: p=0.784 H₁: p<0.784 OF. Ho: p>0.784 H₁: p=0.784
