Construct a scattergram for each data set. Then calculate r andr 2 for each data set. Interpret their values. Complete parts athrough d

a.	x	−1	0	1	2	3
	y	−3	0	1	4	5

Calculate r.

r=. 9853 ​(Round to four decimal places as​ needed.)

Calculate r2.

r2=0.9709. ​(Round to four decimal places as​ needed.)

Interpret r. Choose the correct answer below.

A.There is not enough information to answer this question.

B.There is a very strong negative linear relationship between xand y.

C.x and y are not related.

D.There is a very strong positive linear relationship between xand y. Your answer is correct.
