Answer question A and B using regression analysis. Do not use excel a. A real estate appraiser wants to use square footage of living area, assessed value, and number ofooms to predict the sale price of home.Identify the dependent and independent variables.Write the equation of regression model that can be used to make the prediction. b. Emma's Extreme Sports hires hang-gliding instructors and pays them a fee of $50 per class aswell as $20 per student in the class. The total cost Emma pays depends on the number of students ina class. Find the equation that expresses the total cost in terms of the number of students in a class.

The independent variables are defined as the variables that essentially influence other variables,…
