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 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 16-4. The multiple coefficient of determination is
A)0.2
B)0.5
C)0.333
