Calculate the forecast using the regression equation


Historical demand for a product is:

Demand
January 12
February 11
March 15
April 12
May 16
June 15

(a) Using a weighted moving average with weights of 0.60, 0.30, and 0.10, find the July forecast.

(b) Using a simple three-month moving average, find the July forecast.

(c) Using single exponential smoothing withα = 0.2 and a June forecast = 13, find the July forecast. Make whatever assumptions you wish.

(d) Using simple linear regression analysis, calculate the regression equation for the preceding demand data.

(e) Using the regression equation in d, calculate the forecast for July."
