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, Raina 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 Raina has to work with. (In the chart, a "sample" is a collection of daily sales figures, in dollars, from this past year for a particular salesperson.) Sample Sample Sample size Groups mean variance Salesperson 1 Salesperson 2 124 200.1 2502.7 116 213.1 2496.6 Salesperson 3 130 214.2 2130.9 Salesperson 4 150 214.7 2694.3 Send data to calculator v Send data to Excel Raina's first step is to decide if there are any significant differences in the mean daily sales of her salespeople. (If there are no significant differences, she'll split the bonus equally among the four of them.) To make this decision, Raina will do a one-way, independent-samples ANOVA test of equality of the population means, which uses the following statistic. Variation between the samples F= Variation within the samples For these samples, F =2.52. (a) Give the p-value corresponding to this value of the F statistic. Round your answer to at least three decimal places. (b) Can we conclude, using the 0.05 level of significance, that at least one of the salespeople's mean daily sales is significantly different from that of the others?
