Seminar for Applied Statistics
A restaurant located in an densely populated US city decides to go for an aggressive marketing campaign so that it improves its business. Every week it advertises in the local newspaper and television. To measure how well the advertising is working, the restaurant owner recorded the weekly gross sales for 35 weeks before the campaign began and the weekly sales for 24 weeks after the campaign began. The data are recorded in Restaurant.sav (Sales: weekly sales in thousand dollar; and Period: period of the sales where 1: before the campaign and 2: after the campaign began).
Use appropriate descriptive statistics, hypothesis testing and confidence interval to analyze the data and find out if the advertising campaign was successful in improving the restaurant’s business. Check the assumptions of the procedure you have used and write a report describing your work.
