According to the National Eye Institute, 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.(Without using z-value)
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 8% as the probability of being colorblind, find a 95% confidence interval for the number of men in a sample of 125 who are colorblind.

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%.

Approximately 8% of males experience red-green color blindness.
Suppose a random sample of 200 men is chosen. a. Assuming the
necessary conditions are satisfied, give the mean and standard
deviation of the Normal model that would be used to approximate the
sampling distribution of the sample proportion of red-green color
blindness. b. Sketch and clearly label the sampling distribution,
based on the 68-95-99.7 Rule. c. Suppose the 200 person sample had
a sample proportion of 10%. What is the probability...

students nation-wide engage in “binge drinking” behavior, that is
having 5 or more drinks in one occasion during the past two weeks.

at her college who binge drink is different than the national
proportion.
