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 α=0.05, determine whether there is sufficient evidence to conclude that some exhibits are less popular than others.  Animal Exhibits at the Zoo   Elephants Lions/Tigers Giraffes Zebras Monkeys Birds Reptiles Number of visitors     139     136    169   125    174  137    174Copy Data    Step 3 of 4 :   Compute the value of the test statistic. Round any intermediate calculations to at least six decimal places, and round your final answer to three decimal places.
