Compute the following sample sizes. Use the appropriate formula.  If necessary, round to the nearest hundredth. In a study of red/green color blindness, 500 men and 2100 women were randomly selected and tested. Among the men, 45 had red/green color blindness. Among the women, 6 have red/green color blindness. Let population 1 be the men and population 2 be the women. a. Construct a 99% confidence interval for the difference between the color blindness proportions of men and women. b. Now interpret this interval. Can we say anything about the proportion of men who are color blind compared to the proportion of women who are color blind?

The figure to the right shows the results of a survey in which 1018 adults from Country​ A, 1025 adults from Country​ B, 1005 adults from Country​ C, 999 adults from Country​ D, and 999 adults from Country E were asked whether national identity is strongly tied to birthplace. Construct a 95​% confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed. The 95​% confidence interval for the proportion of adults from Country A who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country B who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country C who say national identity is strongly tied to birthplace is (____),(____) The 95​% confidence interval for the proportion of adults from Country D who say national identity is strongly tied to…
