n a recent court case it was found that during a period of 11 years888people were selected for grand jury duty and39%of them were from the same ethnicity. Among the people eligible for grand jury duty,80.4%were of this ethnicity. Use a0.01significance 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.

Given information-
Sample size, n = 888
Significance level, α = 0.01
Population proportion, p = 0.804
We have to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury.
So, it is two-tailed test hypothesis.
Hypothesis Formulation-
Null Hypothesis, H0: p = 0.804
Alternate Hypothesis, Ha: p ≠ 0.804
