Recently, a study was conducted in which a random sample of hospitals was selected from each of four categories of hospitals: university related, religious related, community owned, and privately owned. At issue is the hospital charges associated with outpatient gall bladder surgery. The following data are in the file called Hospitals:

a. Compute the average charge for each hospital category.
b. Construct a bar chart showing the averages by hospital category.
c. Discuss why a pie chart would not in this case be an appropriate graphical tool.
