Answer:
<em>(4). is the correct answer</em>
Step-by-step explanation:
(- 3, 1, 1)
(1). - 3 - 1 - 1 ≠ - 2 not an answer...
(2). - 3 - 1 + 3(1) ≠ 2 not an answer...
(3). 4( - 3) + 1 - 3(1) ≠ - 4 not an answer...
<em>(4). 2(- 3) + 3(1) + 4(1) = 1 </em>
<em>3(1) + 3(1) = 6 </em>
<em>- 3 = - 3(1) </em>
So we first have to find the mean: 41+ 38+19+ 30 +21+ 53+34+34 + 37+ 29+ 50 + 43+ 57+ 28+ 50 = 534 534/15 = 35.60
86+ 15+ 75+ 40+ 51+ 60+ 27+ 45+ 112+ 7+65+ 31+ 18+ 27+ 69 = 728728/15 = 48.53
Therefore, the store with the better representation of there data would be the competitor's store. This is because more money is being spent at the competitor's store which has an average of $49.00 when the owners store has an average of $36.00.
Hope this helps.
