The F distribution was used to find the P-value because we performed a one-way ANOVA with five groups and forty subjects. The degrees of freedom for the F distribution were (4,35) because there were four degrees of freedom for the between-group variation (numerator) and 35 degrees of freedom for the within-group variation (denominator).
