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

x1	x2	Y
29	12	94
46	10	108
24	18	112
50	16	178
41	5	95
51	19	176
75	8	170
37	12	118
60	13	143
77	17	212

The estimated regression equation for these data is y= -15.40 +1.91x1 +4.82x2

Here SST = 15,262.4, SSR = 14,164.5, sb1 = 0l2356, and sb2 = 0.9187

a. Test for a significant relationship among x1, x2, and y. Use a = .05.

F = ???

b. Is B1 significant? Use a =0.05

tB1= ???

c. Is B2 significant? Use a =0.05

tB2= ???
