Question
Nicole Scott 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, Nicole 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 Nicole 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.)

Nicole'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, Nicole 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 1.62 .
(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 0.10 level
of significance, that at least one of the
salespeople's mean daily sales is
significantly different from that of the
others?
Yes C No
