Question

A consumer researcher gave consumers a sample shampoo. After using the
shampoo, each consumer used an interval-level scale to rate his or her satisfaction with it. Scores could range from 0 to 100, with higher scores indicating greater satisfaction. Consumers didn’t know each other and were randomly assigned to three groups: (1) receive a store brand of shampoo in a bottle clearly labeled as such, (2) receive a premium brand of shampoo in the premium brand’s bottle, or (3) receive a store brand of shampoo in the premium brand’s bottle. Here are the collected data:

Store brand, store bottle	Premium brand, premium bottle	Store brand, premium bottle
70	85	85
65	90	80
65	95	90
60	90	85
M = 65 s = 4.08	M = 90 s = 4.08	M = 85 s = 4.08

SSbetween = 1400
