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 not given any protein and that did not take agent X<sub>2</sub> is A) 36.7 B) 34.3 C) 36 D) 38.4

The Answer of 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 1 ), and whether or not agent X 2 (a proposed life extending agent) was added to the rats diet (X 2 = 0 if agent X 2 was not added, and X 2 = 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 not given any protein and that did not take agent X₂ is A)36.7 B)34.3 C)36 D)38.4
