Question

From 80 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 α = .05, is per-person spending independent of percent of sales from potstickers?

	Potsticker % of Sales
Per-Person Spending	Low			Medium			High			Row Total
Low		17			10			5			32
Medium		9			13			4			26
High		4			4			14			22
Col Total		30			27			23			80

Calculate the chi-square test statistic, degrees of freedom, and the p-value. (Round your test statistic value to 2 decimal places and p-value to 4 decimal places. Leave no cells blank - be certain to enter "0" wherever required.)
