In a recent court case it was found that during a period of 11 years
people were selected for grand jury duty and
%
of them were from the same ethnicity. Among the people eligible for grand jury duty,
%
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 final 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?
- What is the test statistic?
- What is the P value?

is 0.64.
: p = 0.65 against 
: p > 0.65. Use α= 0.05.
