Explain why the expected value of an F ratio is 1.00 when the null hypothesis is true if there is no treatment effect the numerator.

The reason is that the f ratio is balanced due to the numerator and denominator having equal sources of variability.

Explanation:

The expected value of an F ratio is 1.00 when the null hypothesis is true because in a scenario where there is no treatment effect, we have both the numerator and the denominator of the F ratio both measuring equal sources of variability.

Whenever this happens then the F ratio will be balanced and also it will have a value that is near 1.00.
