The estimated regression equation for these data is
ý = -17.54 + 2.00x, + 4.70x2.
Here, SST = 14,995.6, SSR = 13,855.0, s.
= 0.2482, and s
= 0.9526.
(a) Test for a significant relationship among x,, x,, and y. Use a = 0.05.
State the null and alternative hypotheses.
O Ho: B, < B2
H: B1 2 B2
O Ho: B1 * 0 and B2 = 0
H: B = 0 and B, * 0
O Ho: B1 = B2 = 0
H: One or more of the parameters is not equal to zero.
O Ho: B1 > B2
H: B1 S B2
O Ho: B, + 0 and B2 + 0
H: One or more of the parameters is equal to zero.
