If computing a causal linear regression model of Y $=$ a $+$ bX and the resultant r$2$ is very near zero, then one would be able to conclude that

Group of answer choices

Y $=$ a $+$ bX is a good forecasting method.

a multiple linear regression model is not a good forecasting method for the data.

Y $=$ a $+$ bX is not a good forecasting method.

a multiple linear regression model is a good forecasting method for the data.
