Question

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:

ŷ = 36 + .8x₁ − 1.7x₂

Also provided are SSR = 60 and SST = 180.

The test statistic for testing the significance of the model is _____.

a. 5.00

b. .50

c. .25

d. .33
