At a large university, the graduation rate for student athletes was reported to be 0.61. Consider the distribution of sample proportion graduating for random samples of 4 athletes, compared to the distribution for random samples of 20 athletes.
a. Compare the centers of the distributions for 4 versus 20 athletes.
b. Compare the spreads of the distributions for 4 versus 20 athletes. 354 Chapter 8: Sampling Distributions
c. Compare the shapes of the distributions for 4 versus 20 athletes.
