Case 1 Introduction
Over the past years, the demand for 25mm rebars have fluctuatedwith a seasonal pattern being observed.   Since rebarsare manufactured on a “made to order†basis, the VP for Productionwanted an accurate forecast for the second half of this year 2015,to enable them to plan and schedule the ordering and the storage ofthe raw materials needed for the production. Demand for the 25 mmrebars for last year (2014) were as follows:
Demand for the year 2014
x | y |
January | 3000 |
February | 3500 |
March | 4800 |
April | 4300 |
May | 2400 |
June | 2700 |
July | 3500 |
August | 3500 |
September | 1700 |
October | 2100 |
November | 3200 |
December | 2700 |

Based on the data above, using simple linear regression withseasonality, compute the forecasts for the months of July, August,September, October, November and December of 2015.
