ATen estimates
BTwo estimates
COne estimate
DFour estimates
Answer & Solution
Correct answer: B. Two estimates
1. The F ratio is a comparison, so it needs two numbers.
2. To calculate the F ratio, estimates of the variance are made.
3. Two estimates of the variance are made.
4. One is the variance between samples and one is the variance within samples.
