How to solve this problem? 1. A department store, A, has four competitors: B, C, D, and E. Store A hires a consultant to determineif the percentage of shoppers who prefer each of the five (5) stores is the same. A survey with 1100randomly selected shoppers is conducted, and below are the results of which one of the store'sshoppers prefer. Is there enough evidence using a significance level a = 0.05 to conclude that theproportions are really the same?

We assume that the die is unbiased (upon rolling the die, eachoutcome is equally likely). An experiment is conducted in which the die is rolled 240 times, Theoutcomes are in the table below.
