The p-value 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 Yes
Construct the 99% confidence interval for the difference between the color blindness rates of men and women: (p1 Pz)
Which of the following is the correct interpretation for your answer in part 2? A. 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 B. There is 99% chance that that the difference between the rates of red/green color blindness for men and women lies in the interval C. We can be 99% confident that the difference between the rates of red/green color blindness for men and women lies in the interval D. None of the above
