If You're Running a Multiple Regression of Employee Hours Worked $\frac{\sum_{i=1}^{N}\left(\text { Hours }_{i}-b-m_{1} \text { Tenure }_{i}-m_{2} M B A_{i}\right)}{N}$

Multiple Choice

If you're running a multiple regression of employee Hours Worked on Tenure (in number of years) and MBA (a binary variable equal to 1 for an employee with an MBA, 0 otherwise) , what moment conditions would not be used?

A)
$\frac{\sum_{i=1}^{N}\left(\text { Hours }_{i}-b-m_{1} \text { Tenure }_{i}-m_{2} M B A_{i}\right) }{N}$ = 0
B)
$\frac{\left. \sum _ { i = 1 } ^ { N } \text { Hours } _ { i } - b - m _ { 1 } \text { Tenure } _ { i } - m _ { 2 } \text { MBA } _ { i } \right) \text { Tenure } _ { i }}{N}$ = 0
C)

$\frac{\sum _ { i = 1 } ^ { N } \left( \text { Hours } _ { i } - b - m _ { 1 } \text { Tenure } _ { i } \right) M B A _ { i }}{N}$ = 0
D) $\frac { \sum _ { i = 1 } ^ { N } e _ { i } } { N }$ = 0
