svet-max [94.6K]

Answer: -0.64

Step-by-step explanation:

We know that the coefficient of determination  in a simple linear regression model is denoted by r^2, 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.

r^2= 0.64\\\\\Rightarrow\ r=\sqrt{0.64}=\pm 0.64

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

Then, the correlation coefficient = -0.64
