In a study of red/green color blindness, 1000 men and 2550 women are randomly selected and tested. Among the men, 90 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.

Color Blindness in Men and Women: In a study of red/green color blindness, 500 men and 2100 women are randomly selected and tested. Among the men, 45 have a red/green color blindness. Among the women, 6 have a red/green color blindness. Is there sufficient evidence to support the claim that men have a higher rate of red/green color blindness that women? Conduct the appropriate test at the alpha =.01 level. Is there one or two populations in this problem? Is...
1. In a study of red/green color blindness, 750 men and 2700 women are randomly selected and tested. Among the men, 66 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....
