He hypothesizes that bicycle sales (SALES) are a function of three factors: the population under 20 (POP), the level of disposable income (INCOME), and the number of dollars spent on advertising (ADV). All data are measured in millions of units. Hilton gathers data for the last 20 years. Which of the follow regression equations correctly represents Hilton’s hypothesis? A. SALES = α x β1 POP x β2 INCOME x β3 ADV x ε. B. INCOME = α + β1 POP + β2 SALES + β3 ADV + ε. C. SALES = α + β1 POP + β2 INCOME + β3 ADV + ε. |
