Question

xy12364468710 a. Construct a scatterplot. b. Is there a linear association, nonlinear association, or no association? c. Compute r. d. On the basis of the scatterplot and r, determine the strength of the association? Explain.

Answer 1

SOLUTION:

(a) From the given table, we are to construct a scatterplot.

(b) There is a strong linear association because all the points align themselves in a near perfect straight line.

(c) To Compute r;

(d) We are to determine the strength of the association;

Because r = 0.9934 which is very close to 1.0, so we conclude that the strength of the association is very strong.
