Question

Historical demand for a product is as follows:

  DEMAND
April 60
May 55
June 75
July 60
August 80
September 75
  1. Using a simple four-month moving average, calculate a forecast for October.

    Note: Round your answer to 1 decimal place.

     
  2. Using single exponential smoothing with α = 0.2 and a September forecast = 65, calculate a forecast for October.

    Note: Round your answer to the nearest whole number.

     
  3. Using simple linear regression, calculate the trend line for the historical data. Say the X axis is April = 1, May = 2, and so on, while the Y axis is demand.

    Note: Round your intercept value to the nearest whole number and slope value to 2 decimal places.

     
  4. Calculate a forecast for October using your regression formula.

    Note: Round your answer to 2 decimal places.
