Find the Expectation of an F-distribution with degrees of freedom = 7 and = 8.
Answer and explanation
Correct answer C
The expectation is 4/3. For an F-distribution with denominator degrees of freedom greater than 2, the mean is the denominator degrees of freedom divided by that number minus 2. Thus the mean is 8/(8 − 2) = 8/6 = 4/3.
