Using what you have learned in Chapter 15, answer the following questions.

A psychologist examining art appreciation selected an abstract paining that had no obvious top or bottom. Hangers were placed on the paining so that it could be hung with any one of the four sides at the top. The paining was shown to sample of n=50 participants, and each was asked to hang the paining in the orientation that looked correct. The following data indicate how many people chose each of the four sides to be placed at the top. Are any of the orientations selected more (or less) often than would be expected simply by chance? Test with alpha=.05
