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. = 36 + 0.8x₁ - 1.7x₂

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.

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 (x<sub>1</sub>) , and whether or not agent x<sub>2</sub> (a proposed life extending agent) was added to the rats diet (x<sub>2</sub> = 0 if agent x<sub>2</sub> was not added, and x<sub>2</sub> = 1 if agent was added.) From the results of the experiment, the following regression model was developed. = 36 + 0.8x<sub>1</sub> - 1.7x<sub>2</sub> Also provided are SSR = 60 and SST = 180. -Refer to Exhibit 16-4.
