question 22

Multiple Choice

The following model $y = \beta _ { 0 } + \beta _ { 1 } x _ { 1 } + \beta _ { 2 } x _ { 2 }$ + $\varepsilon$ is used whenever the statistician believes that, on average, y is linearly related to:

• A) \(x _ { 1 }\) , and the predictor variables do not interact.
• B) \(x _ { 2 }\) , and the predictor variables do not interact.
• C) \(x _ { 1 }\) and the predictor variables do not interact or to \(x _ { 2 }\) , and the predictor variables do not interact.
• D) \(x _ { 1 }\) and the predictor variables do not interact and to \(x _ { 2 }\) , and the predictor variables do not interact.
