I need help with some computations

A research was interested in testing the effects of caffeine on word recall. For the study the researcher recruited 24 males and 24 females from 18-30 years of age and 24 males and 24 females over 65 years of age. Within each age and gender, 6 participants were randomly assigned to one of 4 doses of caffeine, either a placebo, 1 cup of coffee, 2 cups of coffee or 3 cups of coffee. So we end with a 2 (age) x 2(gender) x 4(Caffeine) design with 6 people in a group. The data for the study is listed below.
