An experimenter wanted to test the hypothesis that women who eat large meals are not liked as well as women who eat smaller quantities of food by using the one factor repeated measures design. Participants in the study watched a videotape of a woman eating a small nutritious snack, a normal meal, or a huge meal while talking to another person. Each participant viewed three different versions of

After viewing the videotape, participants filled out a questionnaire about how much they liked each of the women they had seen in the videos. In this experiment, the null hypothesis would state that _____.
a. women are not liked differently if they eat different amounts of food
