You are a demand planner and use linear regression to forecast daily demand of a product.

The regression that you develop has the following equation:

Forecast $=2700-260**$ Demand Period

where the demand period is measured in days.

Using this equation, the forecast for the next period will be:

a $2700$ units higher

b $260$ units higher

c $2440$ units lower

d $260$ units lower

e $2960$ units higher
