Multiple choice question based on multiple regression.

Below you are given a partial Minitab output based on a sample of 25 observations.

Coefficient Standard Error

Constant	145.321	48.682
X1	25.625	9.150
X2	-5.720	3.575
X3	0.823	0.183

1. The estimated regression equation is

Y = b0 + b1X1 + b2X2 + b3X3 + e

E(Y) = b0 + b1X1 + b2X2 + b3X3

= 145.321 + 25.625X1 - 5.720X2 + 0.823X3

= 48.682 + 9.15X1 + 3.575X2 + 0.183X3

2. The t value obtained from the table to test an individual parameter at the 5% level is

1. 2.06
2. 2.069
3. 2.074
4. 2.80
