The following data represent the results of an analysis of the proportion of people who use Master Card during a typical shopping trip in three different cities. The sample size was 500 in each city: City A: 70% City B: 60% City C: 65%

A Chi-Square analysis rejected the hypothesis that the proportions in the populations of each city were the same. The calculated Chi-Square value was 10.73 and the value from the Chi-Square table was 5.991.

Is there a difference in the populations of Cities A and B? You must show how you arrived at your conclusion to receive credit for the problem.
