QUESTION $1$

Consider two models. Model $1$: annual salary $={}_0+{}_1$ education $+{}_2$ experience $+e.$

Model $2$: monthly salary $={}_0+{}_1$ education $+{}_2$ experience $+e.$ You estimate both models

$on$ the same sample. Note that $in$ Model $2,$ monthly salary $is$ defined $as$ annual salary divided $by$

When comparing estimates $of$ Model $2to$ estimates $of$ Model $1,$ the following must $be$ true:

$A.$ All coefficients will $be$ different

$B.$ Only intercept coefficients will $be$ different

$C.$ Only slope coefficients will $be$ different

$D.$ There will $beno$ change

$E.$ Only coefficients $on$ education will $be$ different

$A.$ All coefficients will $be$ different

$B.$ Only intercept coefficients will $be$ different

$D.$ There will $beno$ change

$E.$ Only coefficients $on$ education will $be$ different
