Question

The two regression coefficients are -2.7 and -0.3 and the coefficient of correlation is 0.90. Comment

Answer 1

According to the question, both the values of regression coefficient are positive values

So,  

By this formula if we observe carefully if both the values of the coefficients are positive then the gamma will also be positive

So it actually depends on the regression coefficients signs.

That is why 0.90 value is comming as positive because both the values of regression coefficient are positive.

Answer 2

The correct answer is the model is good fit.

• The model is a good fit for the two regression coefficients, -2.7 and -0.3, and the coefficient of correlation is 0.90, because the data can be fitted to the regression line. The correlation coefficient is 0.90.
• The correlation between X and Y variables is positive.
• High correlation value depicts less regression.

Hence, the model is good fit.
