At a large university, the graduation rate for the general student body was reported to be 0.66. Consider the distribution of sample proportion graduating for random samples of 5 students, compared to the distribution for random samples of 50 students.
a. Compare the centers of the distributions for 5 versus 50 students.
b. Compare the spreads of the distributions for 5 versus 50 students.
c. Compare the shapes of the distributions for 5 versus 50 students.
