Nine percent of men and 0.25% of women cannot distinguish between the colors red and green. This is the type of color blindness that causes problems with traffic signals. (a) If 9 men are randomly selected for a study of traffic signal perceptions, find the probability that between 2 and 4 inclusive of them have this type of color blindness. (b) In a group of 180 men, find the mean number that are color blind. (c) In a group of 180 men, find the standard deviation of the number that are color blind. (d) Suppose that a group of 180 men are randomly selected, and 27 of them are color blind. Is this a significantly high number that would perhaps suggest that the given percentage of men that are color blind (i.e., 9%) is not correct?
