Question 2
10.33b: Provide the p-value of the test, and your
reasoning
Hint: See L-20 Pdf Presentation and Lecture: p 6-7 (Exercise
10.35)
p-value=D0.385>0.05àFail to reject HO. There is
significant evidence that the age distribution of
jurors and the countywide age distribution are
similar
p-value=0.019<0.05àReject HO. There is significant
evidence that there is a difference between the
age distribution of jurors and the countywide age
distribution
p-value=0.385>0.05àFail to reject H0. There is
insufficient evidence that there is a difference
between the age distribution of jurors and the
countywide age distribution
p-value=0.019<0.05--> Reject HO .There is
