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= o 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: y=36+.8x1-1.7x2 Also provided are SSR = 60 and SST = 180. The model O a. is significant O b. is not significant O c. Not enough information is provided to answer this question. O d. None of these answers are correct.

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:
|j =36 + .8x1− 1.732
Also provided are SSR = 60 and SST = 180.
The model
O a. is significant
O b. is not significant
O c. Not enough information is provided to answer this question.
O d. None of these answers are correct.
