Title: Help with statistics problem Post by: Biala on Jul 28, 2019 In a recent court case it was found that during a period of 11 years 873 people were selected for grand jury duty and 42% of them were from the same ethnicity. Among the people eligible for grand jury duty, 78.7% 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.
