1. A report in a national magazine estimated that 39 percent of American husbands do not know the color of their wives' eyes. Bill Cornett is a marriage counselor in a clinic in New Orleans. He feels the figure is higher for husbands in the greater New Orleans area. A sample of 264 husbands in this area yielded 111 who did not know the true color of their wives' eyes. a. Conduct a test of significance to determine whether the value of 0.39 can be rejected as too low for husbands in New Orleans. Be sure to state your hypotheses, all relevant statistics, a list of technical conditions, and a conclusion to your test. b. Produce a relevant confidence interval designed to capture the true proportion of American husbands who do not know the color of their wives' eyes. Explain how your interval backs up the result of your test of significance from part a.
