Multiple Choice

i. The random variable for a Poisson probability distribution is discrete. ii. The Poisson probability distribution is always negatively skewed.

• A) (i), (ii), and (iii) are all correct statements.
• B) (i) is a correct statement but not (ii) or (iii).
• C) (i) and (iii) are correct statements but not (ii).
