Question

Regression analysis. Use any software

Answer 1

3.

Equation;

`f(x)=1.1x+0.3`

r-value

r = 1

4.

Equation;

`y=2.5828x+1.4369`

r-value

r = 0.9823

Explanation:

We perform a simple linear regression analysis in megastat software to determine the regression equation. The variable x is assumed to be the independent variable while y the dependent one. The megastat output gives both the regression equations as well as the associated correlation coefficients.
