Question

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?

1. Is this a problem about quantitative or qualitative data?

2. Will you use the t stats or proportion stats option in StatCrunch to complete this problem?

3. State the null and alternative hypothesis using the correct statistical symbols.

4. State the test statistic

5. State the P-value

6. In a complete sentence, indicate the strength of this P-value and five a conclusion using the context of the problem that you are testing. I should be a able to read your conclusion and tell that you were testing about color blindness between men and women.

7. Construct a 99% confidence interval to estimate the difference between the color blindness rates of men and women
