For the two-factor experiment described in the previous question, assume that, as shown, mean bar press rates of either 4 or 8 are identified with three of the four cells in the 2 × 2 table of outcomes.

Furthermore, just for the sake of this question, ignore sampling variability and assume that effects occur whenever any numerical differences correspond to either food deprivation, reward amount, or the interaction. Indicate whether or not effects occur for each of these three components if the empty cell in the 2 x 2 table is occupied by a mean of

A. 12
