t is known that 37% of new freshmen at State University willgraduate within 6 years. Suppose we take a random sample of n=64new freshmen at State University. Let X = the number of thesesampled freshmen who graduate within 6 years. (Do not use a normalapproximation for this problem. This is a binomial problem.)a) What is the probability that X < 29? b) What is the probability that28 ≤ X ≤ 31? c) What is the probability that X = 31? d) What is the expected value of X? e) What is the variance of X? f) Copy your R script for the above into the text box here.
