Question

question #20
create a scatterplot of the following data set. then, determine whether a quadratic regression equation would be an appropriate fit to the data.

x	0	3	4	3	4	7	7	8	9	10
y	164	398	447	389	444	491	498	492	464	442

yes, because the scatterplot takes the shape of a parabola, a quadratic equation would be an appropriate fit to the data.
yes, because the scatterplot takes the shape of a straight line, a quadratic regression equation would be an appropriate fit to the data.
no, because the scatterplot takes the shape of a parabola, a quadratic equation would not be an appropriate fit to the data.
no, because the scatterplot takes the shape of a straight line, a quadratic regression equation would not be an appropriate fit to the data.

Explanation:

A quadratic regression is appropriate for data that follows a parabolic - shaped pattern. A straight - line pattern is better modeled by linear regression.

Answer:

A. Yes, because the scatterplot takes the shape of a parabola, a quadratic equation would be an appropriate fit to the data.
