​(a) Draw a scatter diagram of the data. Choose the correct graph below.

A.

010020xy

A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 2. The following 5 points are plotted, listed here from left to right: (2, 4); (4, 8); (7, 12); (7, 14); (8, 18).

B.

010020xy

A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 4); (4, 8); (7, 12); (7, 9); (8, 18).

C.

A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 2. The following 5 points are plotted, listed here from left to right: (2, 18); (4, 14); (7, 12); (7, 8); (8, 4).

D.

010020xy

A scatter diagram has a horizontal x-axis labeled from 0 to 10 in increments of 1 and a vertical y-axis labeled from 0 to 20 in increments of 1. The following 5 points are plotted, listed here from left to right: (2, 18); (4, 9); (7, 12); (7, 8); (8, 4).

​(b) By​ hand, compute the correlation coefficient.

The correlation coefficient is

requals=nothing.

​(Round to three decimal places as​ needed.)

​(c) Determine whether there is a linear relation between x and y.

Because the correlation coefficient is

negative

positive

and the absolute value of the correlation​ coefficient,

nothing​,

is

greater

not greater

than the critical value for this data​ set,

nothing​,

no

a negative

a positive

linear relation exists between x and y.
