Question: 31. Alternative Method of Testing a Claim About p In a study of perception, 80 men are tested and 7 are found to have red

31. Alternative Method of Testing a Claim About p In a study of perception, 80 men are tested and 7 are found to have red green color blindness (based on data from USA Today). We want to use a 0.01 significance level to test the claim that men have a red green color-blindness rate that is greater than the 0.25% rate for women.

a. Why can’t we use the methods of this section?

b. Assuming that the red green color-blindness rate for men is equal to the 0.25%

rate for women, find the probability that among 80 randomly selected men, at least 7 will have that type of color blindness. Describe the method used to find that probability.

c. Based on the result from part (b), what do you conclude?
