Weapons and Aggression (WA) case study

(WA) Recall that the hypothesis is that a person can name an aggressive word more quickly if it is preceded by a weapon word prime than if it is preceded by a neutral word prime. The first step in testing this hypothesis is to compute the difference between (a) the naming time of aggressive words when preceded by a neutral word prime and (b) the naming time of aggressive words when preceded by a weapon word prime separately for each of the 32 participants. That is, compute an - aw for each participant.

a. (WA) Would the hypothesis of this study be supported if the difference were positive or if it were negative?

b. What is the mean of this difference score?

c. What is the standard deviation of this difference score? d. What is the 95% confidence interval of the mean difference score?
