From 90 of its restaurants, Noodles & Company managers collected data on per-person sales and the percent of sales due to "potstickers\" (a popular food item). Both numerical variables failed tests for normality, so they tried a chi-square test. Each variable was converted into ordinal categories {low, medium, high) using cutoff points that produced roughly equal group sizes. At a = 10, is per- person spending independent of percent of sales from potstickers?
