Suppose we omit X2 from the following in a bivariate model
Yi = 0 + 1X1i + i
And suppose X2 is positively related to X1 and 2 is positive, while 1 is negative. What is the likely effect of omitting X2 on our estimate of 1?
A) No effect; 1 hat will be unbiased.
B) 1 hat will be more negative than it should be.
C) 1 hat will be less negative than it should be.
D) 1 hat will be biased toward zero.
