Exhibit 13-12
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. Also provided are SSR = 60 and SST = 180.

Exhibit 13-12
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 13-12 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. Also provided are SSR = 60 and SST = 180. -Refer to Exhibit 13-12. The life expectancy of a rat that was given 3 units of protein daily, and who took agent X<sub>2</sub> is A) 36.7 B) 36 C) 49 D) 38.4
