A manufacturing company would like to assess the effectiveness of the advertisement campaign that is currently using in order to increase the sales of its products. The campaign includes both printed form of advertisements and advertisements through the radio. During a trial period of about one month they collected data for 22 consecutive weeks. The company spent different amounts for advertising in those weeks using at least one of the two kinds of advertisements. The sales (denoted by sales) are measured in thousands of dollars and so are the amounts spent for printed forms of advertisements (denoted by print_ad) and through the radio (denoted by radio_ad). Some of the results of the analysis are given below.
