F-ratio and p-value

To do the ANOVA analysis you actually need the F-ratio and the corresponding p-value. These are easy to calculate now that you have everything else.

Remember the formula to calculate the F-ratio is given by

$$ \begin{aligned} F & = \frac{ms_a}{ms_{s\times a}}\end{aligned}$$

Calculate the F-ratio using your previous results.
Calculate the corresponding p-value using pf(). First you have to fill in the value of the F-ratio. Complete the command by filling in the correct number of degrees of freedom for the F-distribution: df1 and df2 for the second and the third arguments, respectively.
