Answer 1

For a data set regression equation is y = 36 - 4x, the correlation coefficient for the data is negative

Step-by-step explanation:

The given regression equation is

$y=36-4x$

Here,

$b_0=36$

And, $b_1=-4$

We know that

For a simple linear regression, correlation coefficient is the square root of the coefficient of determination, with the sign of the correlation coefficient being the same as the sign of b1

Here, sign of b1 is negative

Therefore, the correlation coefficient for the data is negative
