The management of the local zoo wants to know if all of their animal exhibits are equally popular. If there is significant
evidence that some of the exhibits are not being visited frequently enough, then changes may need to take place within the
zoo. A tally of visitors is taken for each of the following animals throughout the course of a week, and the results are
contained in the following table. At a = 0.10, determine whether there is sufficient evidence to conclude that some exhibit
are less popular than others.
