Question 2. What is the standard deviation of the sampling distribution model for the proportion of 450 freshmen that will return to the same school for their sophomore year?

(Round to 3 decimal places)

Question 3. What is the probability that the proportion of these 450 freshmen that return to the same school for their sophomore year is less than 0.73?
