Question
Which statement is NOT true for the following regression equation?
Y = 0.4*X1 + 0.8*X2 + 0.6 +e
When x takes on value 0, the predicted Y value is 0.6
On unit change in X1 value is expected to lead to 0.4 unit change in Y value
Since 0.8 > 0.4, we can claim that the influence of X2 on Y is greater than X1
Unless the P value is given, we cannot be sure whether the regression coefficient associate with X1 (0.4) is significant or not
When x takes on value 0, the predicted Y value is 0.6
On unit change in X1 value is expected to lead to 0.4 unit change in Y value
Since 0.8 > 0.4, we can claim that the influence of X2 on Y is greater than X1
Unless the P value is given, we cannot be sure whether the regression coefficient associate with X1 (0.4) is significant or not
Explanation / Answer
Answer: A
Explanation : B, C and D is correct.
B) One unit change in X1 expected to lead 0.4 unit change
C) influence of X2 on Y is greater than X1, BECAUSE OF REGRESSION Coeffecient
D) Unless P value is given we cannot state about significant or insignificant
A is false when x takes on value 0, because the predicted Y value is 0.6 + e
