: Moving Average and forecast Accuracy Below you can find the population of Alberta from 1951 to 2022 (as of October 1st of each year) from Statistcs Canada. Using the data below, answer the following questions: 1. What is the expected ppulation of Alberta in 2023, using the following forecasting methods: 1.a) the Nave method 1.b) The moving average method with 2 periods 1.c) the moving average method with 3 periods 1.d) the moving average method with 4 periods. 2. Calculate the error for each of the methods for each year that you have a forecast for and use the 3 accuracy measures that we learned in class to compare the 4 forecasting methods of parts a-d. (you should add four columns to the table below and calculate the forecasted value for each case. Then you should add 4 more columns to calculate the error for each of the methods. Using the errors you should calculate the MAD, MSE and MAPE for each of the 4 forecasting techniques and state which one is performing better.
