Answer:
Sandra is winning because she is generally closer to the center.
Step-by-step explanation:
We will compare the means of both sets of data. To find each mean, we find the sum of the data points and divide by the number of data points.
For Denise:
(112+116+125+119+131)/5 = 603/5 = 120.6
For Sandra:
(124+120+110+126+118)/5 = 598/5 = 119.6
Since Sandra has the smaller mean, this means on average her scores are closer to center than Denise's. This means she is winning.
Difference is asking you to subtract:
-4 - (-5)
Note that when subtracting, when 2 subtraction signs are in a row, it turns into an addition sign:
-4 + 5
If we rearrange this:
5 - 4
1
Hope this helps!
