From 74 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 14 6 3 23 medium 7 16 5 28 high 3 4 16 23 col total 24 26 24 74 click here for the excel data file (a) the hypothesis for the given issue is h0: percentage of sales and per-person spending are independent. yes no (b) 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.) test statistic d. f. p-value (c) we reject the null and find dependence. yes no
