Question

In a study of red/green color blindness, 850 men and 2750 women are randomly selected and tested. Among the men, 77 have red/green color blindness. Among the women, 8 have red/green color blindness. Test the claim that men have a higher rate of red/green color blindness. The test statistic is The p-value is Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness than women using the 0.01% significance level? A. No B. Yes 2. Construct the 99% confidence interval for the difference between the color blindness rates of men and women. <(p1−p2)< Which of the following is the correct interpretation for your answer in part 2? A. We can be 99% confident that the difference between the rates of red/green color blindness for men and women lies in the interval B. We can be 99% confident that that the difference between the rates of red/green color blindness for men and women in the sample lies in the interval C. There is a 99% chance that that the difference between the rates of red/green color blindness for men and women lies in the interval D. None of the above
