The proportion of Canadians with green eyes is 0.36. As part of a study of the genetic basis for skin sensitivity to sunlight, a research term collects a simple random sample of 300 Canadians. Answer the following questions to 4 places past the decimal.
a) How many people in the sample would you expect to have green
eyes?
b) What is the standard deviation of the sample proportion? (Use
the normal approximation from now on).
c) What is the probability that the sample proportion will exceed 0.3877?
