The study consisted of 8 companies and the data is given below and is in units of $1000s (ie. 2.4 = $2400.00) a. Report dependent and independent variables in this study. Independent variable: ________________________________________________________________ Dependent variable: __________________________________________________________________ Both variables are what type of data? [Circle one:] Numerical Categorical b. Write out the linear model/regression equation using the average money spent on advertising to predict the company sales. Do not round. c. Find the predicted value of company sales when advertising expenditure is $2200.00 (X=2.2).
