Answer

$\quad$ $\qquad$ mean $\quad$ median $\quad$ mode Samuel $\quad$ 22 $\qquad$ 19.5 $\qquad$ 22 Sticker $\quad$ 22 $\qquad$ 22 $\quad$ $\qquad$ 22 Both sales representatives averaged 22 sales per week for those 8 weeks. The median is 19.5 for Samuel and 22 for Sticker. We would expect 19.5 sales from Samuel and 22 sales from Sticker each week. Samuel’s and Sticker’s sales have a mode of 22 for both. Going by the mode we expect 22 sales from each representative for each week.
