The experiment described in Exercise 15.24 was repeated, with the following results.
Combining these data with those of Exercise 15.24, perform an appropriate analysis of variance to test the null hypotheses involving diet foods, laboratories, replicates, and the food-laboratory interaction. Use the 0.05 level of significance.

Use the 0.05 level of significance. With reference to Exercise 15.3, show that the computing formulas for the sums of squares are And Make use of the identity To prove Theorem 15.3. Given a set of k-tuples ( x11, x12, . . ., x1k), ( x21, x22, . . ., x2k), . . ., and ( xn1, xn2, . . ., xnk), the extent of their association, or agreement, may be measured by means of the coefficient of concordance: Where ...
