One group of subjects ze a list of words in the evening just before going to bed. Their recall is tested 10 hours later in are t SUbJeCtS in the Second group memorize the same list of words in the morning, and then their memories ested 10 hours later afler being awake all day.

The recall scores for two samples of college students are as follows: ASLEEP SCORES AWAKE SCORES 15 13 14 14' 15 13 IA i2' 16 15 16 15 14 13' .,Ltf' 12 16 15 17 14 A,l3' t,13' p/n'I'Z l4 M = 15 M = 13 s = 1.13 s = 1.13 (Note that I have provided the means and standard deviations to facilitate hand-calculations.) a. Sketch a frequency distribution polygon for the "asleep" group. On the same graph (in a different color) sketch the distribution for the "awake" group. Just by looking at these two distributions, would you predict a Slgmficant difference between the two treatment conditions? 5) The experiment described the previous problem was repeated using samples of 6-year-old children. The data for this experiment are as follows
