In its February 21 19981 issue. Fortune magazine published the results of a Yankelovich partners survey of 600 adults that investigated their ideas about marriage1 divorce1 and the contributions of the corporate wife. The survey results are shown in Figure 10.16. For each statement in the figure1 the proportions of men and women who agreed with the statement are given. Assuming that the survey results were obtained from independent random samples of 300 men and 300 women: 

a. For each statement, carry out a hypothesis test that tests the equality of the population proportions of men and women who agree with the statement. Use a equal to .10. .051 .011 and .001. How much evidence is there that the population proportions of men and women who agree with each statement differ?

b. For each statement1 calculate a 95 percent confidence interval for the difference between the population proportion of men who agree with the statement and the population proportion of women who agree with the statement. Use the interval to help assess whether you feel that the difference between population proportions has practical significance.
