(d) The F statistics are computed by dividing the mean square for each effect (equal to its sum of squares) by the error mean square 1.04. The degrees of freedom for each F statistic are 1 and 4. The results are summarized in the following table. Sum of Mean Variable Effect DF Squares Square F P A 3 9875 1 63 601 63 601 61 154 0 001 B 2 0375 1 16 606
