Question

Referring to Scenario 11-2, the p-value of the test is SCENARIO 11-2 The dean of a college is interested in the proportion of graduates from his college who have a job offer on graduation day. He is particularly interested in seeing if there is a difference in this proportion for accounting and economies majors. In a random sample of 100 of each type of major at graduation, he found that 65 accounting majors and 52 economics majors had job offers. If the accounting majors are designated as "Group 1" and the economies majors are designated as "Group 2 perform the appropriate hypothesis test using a level of significance of 0.05 e Minimized View 0.0621 0.024 1.245 1.521

Explanation / Answer

Ans:

pooled proportion=(65+52)/(100+100)=0.585

Test statistic:

z=(0.65-0.52)/sqrt(0.585*(1-0.585)*((1/100)+(1/100)))

z=1.866

p-value(two tailed)=2*P(z>1.866)=2*0.03105=0.0621
