Answer:

The correct option is C.

Step-by-step explanation:

The given data table is

  x          y

  2         15

  6         13

  7          9

  8         8

  12        5

Using calculator we get

Mean of x =7

Mean of y =10

SS_x=52

SS_y=64

r=-0.9534\approx -0.953

The correlation coefficient of the data set is -0.953.

Therefore the correct option is C.
