In the morning, after having had nothing to eat since the night before, 75 participants were randomly assigned to one of three groups (25 in each group): Those who were fed a large meal, those who were fed a small meal, and those who were fed nothing. Then all participants were given a memory test. The results were as follows:

Memory Test Score

Large Meal

Small Meal

Nothing

M

2.1

2.5

2.9

S2

1.0

1.2

.8

Based on these results, does amount of breakfast eaten affect memory?
(Use the .05 level.)

Use the five steps of hypothesis testing.

Prior to eating breakfast, 25 participants were randomly assigned to eat a large meal, 25 to eat a small meal, and 25 to eat nothing. Immediately following the meal, all participants took a memory test. The means and estimated population variances for the three groups on the memory test were: Large: M = 2.1, S2 = 1.0; Small: M = 2.5, S2 = 1.2; Nothing: M = 2.9, S2 = 0.8.
