Assume You Ran a Multiple Regression to Gain a Better

question 26

Multiple Choice

Assume you ran a multiple regression to gain a better understanding of the relationship between lumber sales, housing starts, and commercial construction. The regression uses lumber sales (in $100,000s) as the response variable with housing starts (in 1,000s) and commercial construction (in 1,000s) as the explanatory variables. The estimated model is Lumber Sales = β₀ + β₁Housing Starts + β₂Commercial Constructions + ε. The following ANOVA table summarizes a portion of the regression results. The standard deviation of the difference between actual lumber sales and the estimate of those sales is ________.

• A) 29.58
• B) 48
• C) 103.3
• D) 875
