Given that the fitted regression is Y = 75 − 6 X1 + 0.8
X2, the standard error of b1 is 2.5, and n = 23,
at α = .1, can we conclude that X1 is a significant
predictor of Y?
Note that
t0.05 t0.025 t0.01
df=22 1.717 2.074 2.508
df=21 1.721 2.080 2.518
df=20 1.725 2.086 2.528
a.) Not enough information to decide
b.) Yes
c.)No
