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

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
