Color Blindness 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).
a. Construct a 90% confidence interval estimate of the proportion of all men with this type of color blindness.
b. What sample size would be needed to estimate the proportion of male red > green color blindness if we wanted 96% confidence that the sample proportion is in error by no more than 0.03? Use the sample proportion as a known estimate.
c. Women have a 0.25% rate of red > green color blindness. Based on the result from part (a), can we safely conclude that women have a lower rate of red> green color blindness than men?
