In a recent court case it was found that during a period of 11 years 899

people were selected for grand jury duty and

40% of them were from the same ethnicity. Among the people eligible for grand juryduty,

78.6% 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 nullhypothesis, alternativehypothesis, teststatistic, P-value, conclusion about the nullhypothesis, and final conclusion that addresses the original claim. Use theP-value method and the normal distribution as an approximation to the binomial distribution.
