The coefficient of determination in a simple linear regression model is 64%. What is the correlation level between the dependent and independent variables, assuming a negative relationship between them

-0.64

Step-by-step explanation:

We know that the coefficient of determination  in a simple linear regression model is denoted by , which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.

Given, the coefficient of determination in a simple linear regression model is 64%.

i.e.

As there is negative relation between the dependent and independent variables.

Then, the correlation coefficient = -0.64
