To help explain or predict the response variable in every regression study, we use one or more explanatory variables. These variables are also called dependent variables.

A company is going to run a promotional plan for one of its products that recently introduced to market. There are three ways of advertising the promotions: TV, Radio, and Social Media.

A small construction firm specializes in building and selling single-family homes. The firm offers two basic types of houses, model A and model B. Model A houses require 1,000 labour hours, 6 tons of stone, and 2,000 board feet of lumber. Model B houses require 10,000 labour hours, 3 tons of stone, and 2,000 board feet of lumber. Due to long lead times for ordering supplies and the scarcity of skilled and semiskilled workers in the area, the firm will be forced to rely on its present resources for the upcoming building season. It has 600,000 hours of labour, 150 tons of stone, and 300,000 board feet of lumber.  Assume that the firm will be able to sell all the units it builds. Find the total profit for the above problem. The template is given in “Building” excel sheet of “Exam 2- Template” excel file.

In regression analysis, the variable that is predicted or explained by other variables is called the:
