A marketing researcher is interested in finding the most effective way to persuade people. He decides to study two aspects of persuasion: The expertise of the person giving the persuasive measure (high expertise versus low expertise) and the importance of the issue to the targets of persuasion (high importance versus low importance). Expertise and Importance are combined into four treatment groups:
(1) high expertise and high importance
(2) high expertise and low importance
(3) low expertise and high importance
(4) low expertise and low importance
After subjects listen to the persuasive message, they complete a measure of their attitudes on a scale with values ranging from 1 to 30 where higher scores indicate greater levels of attitude change. Please identify all of the statements below that are accurate

True/False: The interaction would examine whether the effect of importance to the subject on attitude change differs depending on the level of expertise

True/False: The main effect of importance would measure whether there is a mean difference between groups 1 and 2

True/False: The main effect of expertise would measure whether there is a mean difference between the average of groups 1 and 2 and the average of groups 3 and 4.

True/False: This study would be analyzed using a two factor ANOVA

True/False: In this study, expertise and importance have been combined factorially.

please help! i've done this multiple times and i still can't figure it out :(
