Given the following data, use least squares regression to derive a trend equation:

Period: 1 2 3 4 5 6

Demand: 9 11 8 12 14 14

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)
