The Regression Equation

In the last lab we tried to predict how much people liked us based on how much money we gave them. This was great and all, but it's unlikely that money alone would have predicted how much our sample liked us. Let's say we want to add a new variable to the model: smiling.

Which of the following is the equation for our new model?

Possible Answers

\(liking = intercept + (b1 * money) + (b2 * smiling)\)
\(liking = (b0 * intercept) + (b1 * money) + (b2 * smiling)\)
\(liking = intercept + (b1 * money) * (b2 * smiling)\)
