Transcribed Image Text:In a recent court case it was found that during a period of 11 years 886 people were selected for grand jury duty and 38% of them were from the same ethnicity.
Among the people eligible for grand jury duty, 78.2% 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.
Which of the following is the hypothesis test to be conducted?
О В. Но: р30.782
О А. Но: р<0.782
H1: p= 0.782
H1:p>0.782
C. Ho: p#0.782
H1: p= 0.782
D. Ho: p= 0.782
H1: p#0.782
Е. Но: р3D0.782
H1: p<0.782
O F. Ho: p>0.782

C. There is sufficient evidence to warrant rejection of the claim that the
selection process is biased against allowing this ethnicity to sit on the
grand jury. The jury selection process appears to be fair.
D. There is not sufficient evidence to support the claim that the selection
process is biased against allowing this ethnicity to sit on the grand jury.
