Discuss the application of multiple regression model using a
real-life example. [Hint: You are supposed to examine a possible
relationship between a dependent and at least three important
independent variables in the example which you have chosen.
Identify dependent variable and independent variable and write the
mathematical regression equation for the example and explain each
component of the equation.]
