A one-way ANOVA (analysis of variance) would be an appropriate procedure to test for significant differences in the average incomes among the three cities. This test compares the means of three or more groups to determine if they are significantly different from one another. Chi-square and paired-samples t-tests are not appropriate for testing differences in means, and a one-sample t-test would only compare the mean of one group to a known value.
