Lexon Inc. is a large manufacturer of affordable DVD players. Management recently became aware of rising expenses resulting from returns of malfunctioning products. As a starting point for further analysis, Paige Jennings, the controller, wants to test different forecasting methods and then use the best one to forecast quarterly expenses for 2019. The relevant quarterly data for the previous three years follow:

2016                       Quarter Return Expenses           2017      Quarter Return Expenses  2018      Quarter Return Expenses

1                                 12000                              1                      12300                   1                    12600

2                                 10800                              2                       11500                  2                     11700

3                                11100                               3                         11100                3                      11500

4                                13100                              4                           13100                  4                   13900

• The result of a simple regression analysis using all 12 data points yielded an intercept of $11,359.09 and a coefficient for the independent variable of $110.14. (R-squared = 0.16, SE = $938.50.)

Required:

Question 1. Plot the data in the order of the dates. (To earn full credit for this graph you must plot all required points for each curve. While plotting the points a tool icon will pop up. You can use this to enter exact co-ordinates for your points as needed.)

• in the x-axis quarter (0,2,4,6,8,10,12,14)
• in the y-axis return expense (6000, 7000, 8000,..., until 17000
