Transcribed Image Text: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 exhibits are less popular than others.

We reject the null hypothesis and conclude that there is sufficient evidence at a 0.10 level of significance that some exhibits are less popular than
others.
