Task 1: If we use advertising as the predictor variable, we can find a linear regression model which would give estimates of the sales. Which one of the following will the best regression model? Justify your answer.

Table below shows some data from the early days of the Italian clothing company Benetton. Each row in the table shows Benettons sales for a year and the amount spent on advertising that year. In this case, our outcome of interest is salesit is what we want to predict.

• Sales = 22.60 Advertising + 169.2
• Sales = 23.42 Advertising + 167.7
• Sales = 23.10 Advertising + 168.1
