A paired difference experiment is conducted to compare the starting salaries of male and female graduates who find jobs. Pairs are formed by choosing a male and a female with the same major and similar grade-point average. Suppose a random sample of 10 pairs is formed in the same manner, and the starting annual salary of each person is recorded. The results are shown below. Test to see whether there is evidence that the mean starting salary of males exceeds the mean starting salary of females. Use 0.025 level of significance. Pair 1 2 3 4 5 6 7 8 9 10 Male 4,300 6,500 5,400 3,500 8,500 2,800 4,500 6,200 3,400 4,200 Female 3,800 6,600 4,800 3,500 7,600 3,000 2,000 5,100 3,200 3,500
