Explanation Given: The probability that an entering freshman will graduate within 4 years is 0.6 . Number of entering freshmen is 2000 . Approach: Write the expressions to obtaining the mean and standard variation. μ = n p Here, p is the probability that an entering freshman will graduate within 4 years, μ is the mean and n is number of incoming freshemen. Calculation: Calculate the mean of the number of the students who will graduate within 4 years. Substitute 2000 for n , 0 To determine b) The standard deviation of number of students who will graduate within 4 years.
