(a) 0.4 (b) -0.6
(c) 0.36 (d) 0.64

Answer 2

If r = 0.6 then the coefficient of non-determination is 0.64

If 'r' is the correlation coeffcient, the coefficient of non-determination is given as (1 - r²).

In the question above,

the value of correlation coefficient (r) = 0.6, so coefficient of non-determination is [1 - (0.6)²] = (1 - 0.36) = 0.64.

So, the required value is 0.64.
