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.

FOOD DEPRIVATION (Hrs.)

0 24

Reward 1 8

Amount 2 4 8

(Pellets)

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

(b) 8

(c) 4
