B. The F-distribution is defined by three parameters.

C. The two samples used in the F-test must have the same size.

Correct Answer: A

Just like the chi-square distribution, the F-distribution is skewed. This statement is correct; all other statements are incorrect. The F-distribution is defined by two parameters: the numerator and the denominator degrees of freedom. The sample size of the two samples does not have to be equal.
