Using single exponential smoothing with α = 0.20 and a September forecast = 49, calculate a forecast for October
DEMAND April 71 May 66 June 91 July 71 &nbs
| DEMAND | |
| April | 71 |
| May | 66 |
| June | 91 |
| July | 71 |
| August | 96 |
| September | 91 |
1. Using single exponential smoothing with α = 0.20 and a September forecast = 49, calculate a forecast for October.
2.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. (Round your intercept value to the nearest whole number and slope value to 2 decimal places.)
