Question
What is the test statistic?
What is the p value?

Transcribed Image Text:In a recent court case it was found that during a period of 11 years 853 people were selected for grand jury duty and 36% of them were from the same ethnicity.
Among the people eligible for grand jury duty, 78.5% 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. ldentify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and fina
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?
CA. Ho p= 0. 785
B. H, p 0 785
H1 p= 0.785
H1: p<0.785
O C. Ho p=0.785
OD. H, p=0.785
H, p#0.785
H, p>0 785
OE H p>0.785
H: p=0.785
XE
Ho p<0.785
H p=0.785
