Answer 1

Given Age and Score given by them

Let Age be x and Score given is y,

Correlation is given by formula:

ΣΧΥ ΣΧ? ΣΥ2

Where, X = x- mean of x values

Where, Y y- mean of y values

The Correlation is calculated as:

G12 X f =19/SQRT(G9*H9) F G H I Age (x) Y^2 Score (y) X = x-(mean of x) Y = y-(mean of y) X^2 -19 2.5 -3.5 - 1. 5 -0. 5 361 841 64 4 -101.5 6.25 12.25 2.25 0.25 21 1270 - 160 9 Total 10 Mean Correlation | -0.97973

The Formula used was shown in the formula bar.

The Answer is Option D = -0.98
