Quinn’s Video shop has provided you with cross-sectional expenditures data from thirty randomly selected customers (data attached in separate file). He would like to know what impact DVD price has on the monthly expenditures for DVD’s. As control variables, Quinn’s data also includes income the individual earned in the month the data was collected, and the amount that it rained in the month the data was collected. Provide Quinn with a regression analysis that best answers his question. You must justify why this is the best possible regression.
