To get around the problem, we often assume that e, is normally distributed. O D. To fix the problem, we need to have an instrumental variable. O C. This problem implies that errors are correlated with one of O d. If we assume Varlelx)= o?, the confidence interval is not valid. e. None of the above is correct.

Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
