A. individuals, if the population is Normal
B. individuals, if the population is NOT Normal
C. averages based on small n, if the population is Normal
D. averages based on small n, if the population is NOT Normal
E. averages based on large n, if the population is Normal
F. averages based on large n, if the population is NOT Normal
G. count of successes out of n independent trials
H. sample proportion of successes out of n independent trials, when np and n(1-p) is large enough
