Expert Solution
Step 1

The regression analysis is a statistical procedure that allow us to find the linear association between the dependent variable/ outcome variable and one or more independent variables /predictor variables. When there lies linear relationship between the variables, regression analysis will allow us to compute the value of outcome variable using the provided information of predictor variables.
