Matthew is red-green colorblind, meaning that he has a difficult
time distinguishing between red and green hues. Matthew reads
online that approximately 8% of men have this type of
colorblindness. He conducts a random survey of 197 men, and finds
that only 12 of them are red-green colorblind. At the 1%
significance level, conduct and interpret a hypothesis test to
determine if the proportion of men with red-green colorblindness is
less than 8%.

8% of men are red-green colorblind. A sample of 125 men is
gathered from a particular subpopulation, and 13 men in this sample
are colorblind.
a. Is this statistically significant evidence that the
proportion of red-green colorblind men is greater than the
subpopulation than the national average with alpha = 0.05?
b. What is the maximum number of men that could have been
colorblind in this sample that would lead you to fail to reject the
null hypothesis?
c. Using...
