Final answer:
The question requests the projected sales revenue for Coolit at a $10,000 advertising spend, but the regression output data is not provided, making it impossible to give an exact figure.
Step-by-step explanation:
The question asks for the projected sales revenue for Coolit if the company spends $10,000 on advertising. However, the necessary regression output data is not provided in the question text. In a typical scenario where regression analysis is used for sales forecasting, you would apply the $10,000 advertising spend to the regression equation calculated from the past 36 months of sales and advertising data.
A general regression equation is in the form: Sales = (Coefficient for Advertising Spend * Advertising Spend) + Intercept. Without the actual coefficient and intercept values from Coolit's regression output, we cannot calculate the projected sales.
