Hi I know that you can’t answer every question is there anyway you can just answer question 9 please? 3:03Use the following to answer questions 6-8:At a large midwestern university, a simple random sample of100 entering freshmen in 1993 found that 20 of the sampledfreshmen finished in the bottom third of their high school class.Admission standards at the university were tightened in 1995.In 1997, a simple random sample of 100 entering freshmenfound that only 10 finished in the bottom third of their highschool class. Let p, and p, be the proportions of all enteringfreshmen in 1993 and 1997, respectively, who graduated in thebottom third of their high school class.What is a 90% plus four confidence interval for p, -P;?A0.098 + 0.050B)0.098 + 0.083C)0.098 + 0.099D0.098 +0.130Is there evidence that the proportion of freshmen who graduated in the bottom third oftheir high school classes in 1997 has been reduced, as a result of the tougher admissionstandards adopted in 1995, compared to the proportion in 1993? To determine this, testthe hypotheses H: p. -p, versus H: p, >P. What is the value of the z statistic for testingthese hypotheses?A) = 1.20B)E- 1.92C)- 1.96DE-1.988. What is the value of the P-value?AP-value <0.001B)P-value 0.0238C)P-value - 0.025DP-value - 0,1151A review of voter registration records in a small town yielded the following table of thenumber of males and females registered as Democrat, Republican, or some otheraffiliation:GenderAffiliation Male FemaleDemocrat 300 600Republican 500 300Other200 100Suppose we wish to test the null hypothesis that there is no association between partyaffiliation and gender.
