19. The following matrix presents the results of a two- factor study with n = treatment conditions. Note that one of the treatment 10 scores in each of the six means is missing. Factor B B, B, M = 10 M = 20 | M = 40 A, Factor A A, M= 20 | M = 30 a. What value for the missing mean would result in no main effect for factor A? b. What value for the missing mean would result in no interaction? 20. A researcher conducts an independent-measures, two-factor study using a separate sample of n = 15 participants in each treatment condition. The results are evaluated using an ANOVA and the researther reports an F-ratio with df = 1, 84 for factor A, and an F-ratio with df = 2, 84 for factor B. a. How many levels of factor A were used in the study? b. How many levels of factor B were used in the study? c. What are the df values for the F-ratio evaluating B.

2. Suppose that in Example 2.27, 400 units of food A, 500 units of B, and 600 units of C are placed in the test tube each day and the data on daily food consumption by the bacteria (in units per day) are as shown in Table 2.7.
