Lexon Incorporated 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 2022 . The relevant quarterly data for the previous three years follow: The result of a simple regression analysis using all 12 data points yielded an intercept of $11,868.18 and a coefficient for the independent variable of $124.13. ( R-squared = 0.19, SE=$978.74. ?equired: . Looking at the graph you prepared for requirement 1, select two representative data points and calculate the quarterly forecast for 022 using the high-low method. . Calculate the quarterly forecasts for 2022 using the results of a regression analysis. Evaluate the results of the regression analysis ind make appropriate changes to improve the model. (Hint: For Regression Two, use a dummy variable to incorporate seasonality inte he model.) Complete this question by entering your answers in the tabs below. Looking at the graph you prepared for requirement 1, select two representative data points and calculate the quarterly forecast for 2022 using the high-low method. (Do not round intermdiate calculations. Round your answers to the nearest dollar amount.) Calculate the quarterly forecasts for 2022 using the results of a regression analysis. Evaluate the results of the regression analysis and make appropriate changes to improve the model. (Hint: For Regression Two, use a dummy variable to incorporate seasonality into the model.) (Do not round intermediate calculations. Round your final answers to two decimal places.) Lexon Incorporated is a large manufacturer of affordable DVD players.
