Given the following data, use least squares regression to derive a trend equation:
Period: 1 2 9 3 4 5 6
Demand: 7 9 5 11 10 13
The least squares regression equation that shows the best relationship between demand and period is (round your responses to two decimal places)
y ^= (blank) + (blank) x , Where y ^= demand and x= period.
Period 7 forest = (bank)
Period 12 forecast = (blank)
