Consider the following data for a dependent variable y and two independent variables,
x1
and
x2.

The estimated regression equation for these data is
ŷ = −18.37 + 2.01x1 + 4.74x2.
Here, SST = 15,182.9, SSR = 14,052.2,
sb1 = 0.2471,
and
sb2 = 0.9484.

Test for a significant relationship among
x1, x2, and y.
Use ???? = 0.05.
