F-Value: The F-distribution is a probability distribution used to compare variances by examining their ratio.
Thus, the support of the F-distribution is the interval from 0 to |Mathematical Expression Omitted~, and the cumulative distribution satisfies the formula |Mathematical Expression Omitted~.
If this hypothesis is true, then the relevant test statistic has F-distribution with degrees of freedom 3 and 54, respectively.
