18. Consider the following regression equation: Y = 30 + 8X. If
SSE = 600 and SS Total = 1,200. Compute the correlation
coefficient.

Respuesta :

Answer: 0.7071

Step-by-step explanation:

The first thing to do is to calculate the R² which is the coefficient of determination. This will be:

= 1 - SSE/SS Total

= 1 - 600/1200

= 1 - 0.5

= 0.5

Then, the correlation coefficient will be:

= ✓0.5

= 0.7071
