Transcribed Image Text:In a recent court case it was found that during a period of 11 years 871 people were selected for grand jury duty and 37% of them were from the same ethnicity.
Among the people eligible for grand jury duty, 80.7% 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.
What is the test statistic?
z=
(Round to two decimal places as needed.)
