Solution:
We are given
Correlation coefficient = r = 0.57
So, we have
Coefficient of determination = r^{2} = 0.57^2 = 0.3249
Coefficient of determination = 0.32
Coefficient of non-determination = 1 - Coefficient of determination
Coefficient of non-determination = 1 - 0.32
Coefficient of non-determination = 0.68
Answer: 0.68
