Answer explanation
Choice A is correct. The data point with has a y-coordinate of 12. The y-value predicted by the line of best fit at
is approximately 11. The difference between the y-coordinate of the data point and the y-value predicted by the line of best fit at
is
, or 1.
Choices B and C are incorrect and may result from incorrectly reading the sterplot. Choice D is incorrect. This is the y-coordinate of the data point at .
