In a recent court case it was found that during a period of 11 years 882 people were selected for grand jury duty and 36% of them were from the same ethnicity. Among the people eligible for grand jury duty, 80.7% were of this ethnicity. Use a 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 fina 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>0.807 H,: p-0.807 O B. Ho: p-0.807 H:p<0.807 OC. Ho: p=0.807 H: p> 0.807 O D. Ho: p<0.807 H: p-0.807 ОЕ. На: р 0.807 H: p*0.807 OF. Ho: p0.807 H: p=0.807
