From 77 of its restaurants, Noodles & Company managerscollected data on per-person sales and the percent of sales due to\"potstickers\" (a popular food item). Both numerical variablesfailed tests for normality, so they tried a chi-square test. Eachvariable was converted into ordinal categories (low, medium, high)using cutoff points that produced roughly equal group sizes. At α =.01, is per-person spending independent of percent of sales frompotstickers?

(a) The hypothesis for the given issue is H0: Percentage ofSales and Per-Person Spending are independent. No Yes
(b) Calculate the chi-square test statistic, degrees of freedom,and the p-value. (Round your test statistic value to 2 decimalplaces and p-value to 4 decimal places. Leave no cells blank - becertain to enter \"0\" wherever required.) Test statistic d.f.p-value
(c) We reject the null and find dependence. No Yes
