If a random variable is discrete,it means that the outcome for the random variable can take on only one of two possible values.
The actual prices paid per unit of each activity driver were equal to the standard prices. -Refer to the figure.What are the value-added costs for labour?

Assume that the variance depends on a third variable, Wi, which does not appear in the regression function, and that var(ui|Xi,Wi)= θ0+θ1 One way to estimate θ0

The graph of a discrete random variable looks like a histogram where the probability of each possible outcome is represented by a bar.
