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) , which moment conditions would 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) $\frac{\left.\sum_{i=1}^{N} \text { Hours }_{i}-b-m_{1} \text { Temure }_{i}-m_{2} \text { MBA }_{i}\right) \text { Tenure }_{i}}{N}$ = 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) The first two answer options are correct.
