![Exhibit 16-4
In a laboratory experiment, data were gathered on the life span (y in months) of 33 rats, units of daily protein intake (x₁), and whether or not agent x₂ (a proposed life-extending agent)
was added to the rats' diet (x2 = 0 if agent x2 was not added, and x2 = 1 if agent was added). From the results of the experiment, the following regression model was developed:
ŷ = 36 + .8x1 - 1.7x2
