Cannister, Inc., specializes in the manufacture of plastic containers. The data on the monthly sales of 10-ounce shampoo bottles for the past 5 years are as follows:

Chapter 8, Problem 23P, Cannister, Inc., specializes in the manufacture of plastic containers. The data on the monthly sales

  1. Using the multiplicative seasonal method, calculate the monthly seasonal indices.
  2. Develop a simple linear regression equation to forecast annual sales. For this regression, the dependent variable, Y, is the demand in each year and the independent variable, X, is the index for the year (i.e., X = 1 for year 1, X = 2 for year 2, and so on until X = 5 for year 5).
  3. Forecast the annual sales for year G by using the regression model you developed in part (b).
  4. Prepare the seasonal forecast for each month by using the monthly seasonal indices calculated in part (a).

A convenience store recently started to carry a new brand of soft drink. Management is interested in estimating future sales volume to determine whether it should continue to carry the new brand or replace it with another brand. The following table provides the number of cans sold per week. Use both the trend projection with regression and the exponential smoothing​ (let alpha (α)=0.40 with an initial forecast for week 1 of 568​) methods to forecast demand for week 13. Compare these methods by using the mean absolute deviation and mean absolute percent error performance criteria. Does your analysis suggest that sales are trending and if​ so, by how​ much? (i) Obtain the trend projection with regression forecast. The forecast for week 13 is __. (Enter your response rounded to the nearest whole​ number.)   Specify the mean absolute deviation​ (MAD) and mean absolute percent error​ (MAPE). ​(Enter your responses rounded to two decimal​ places.) MAD: ____ MAPE: ____%   ​(ii) Obtain the…
Demand for oil changes at Garcia's Garage has been as follows: Month January February March April May June July August Number of Oil Changes 38 55 56 60 58 01 70 52 a. Use simple linear regression analysis to develop a forecasting model for monthly demand. In this application, the dependent variable, Y, is monthly demand and the independent variable, X, is the month. For January, let X=1; for February, let X 2; and so on. The forecasting model is given by the equation Y=X (Enter your responses rounded to two decimal places)
