Cris Turlock owns and manages a small business in San Francisco, California. The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Cris provides incentives for the four salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Below is a chart giving a summary of the information that Cris has to work with. (A "sample" is a collection of daily sales figures, in dollars, from this past year for a particular salesperson.) Sample Sample size Sample Groups mean variance Salesperson 1 124 225.0 2248.1 Salesperson 2 81 211.5 1984.4 Salesperson 3 90 221.1 2677.9 Salesperson 4 71 211.7 2430.7 Cris performs a gne-way, independent-samples ANOVA test to determine whether or not there is a significant difference in the performances of the different salespeople. (a) This ANOVA IS summarized in the incomplete ANOVA table below. Complete the ANOVA table. (In the table, round your answers for the mean squares to at least one decimal place each, and round your answer for the F statistic to at least two decimal places.)
