Colour Blindness in Men and Women In a study of red/green colour blindness, 500 men and 2100 women are randomly selected and tested. Among the men, 45 have red/green colour blindness. Among the women, 6 have red/green colour blindness (based on data from USA Today). a) Is there sufficient evidence to support the claim that men have a higher rate of red/green colour blindness than women? Use a 0.01 significance level. b) Construct the 98% confidence interval for the difference between the colour blindness rates of men and women. Does there appear to be a substantial difference?
