A psychologist studying artistic preference randomly assigns a group of 45 participants to one of three conditions in which they view a series of unfamiliar abstract paintings. The 15 participants in the Famous condition are led to believe that these are each famous paintings; their mean rating for liking the paintings is 6.5 (S = 3.5). The 15 in the Critically Acclaimed condition are led to believe that these are paintings that are not famous but are very highly thought of by a group of professional art critics; their mean rating is 8.5 (S = 4.2). The 15 in the Control condition are given no special information about the paintings; their mean rating is 3.1 (S = 2.9). Does what people are told about paintings make a difference in how well they are liked? Use the .05 level. Famous: S2 = 12.25 Critically acclaimed: S2 = 17.64 Control: S2 = 8.41 What is the null hypothesis? a. The three groups are the same b. The three groups are different c. Those in the Famous condition are different from those in the Control condition and those in the Critically Acclaimed condition are also different from the Control condition d. Those in the Famous condition are different from those in the Control condition but those in the Critically Acclaimed condition are the same What is the research hypothesis? a. The three groups are the same b. The three groups are different c. Those in the Famous condition are different from those in the Control condition and those in the Critically Acclaimed condition are also different from the Control condition d. Those in the Famous condition are different from those in the Control condition but those in the Critically Acclaimed condition are the same
