Return to Schooling Polynomials(2).png  Refer to Return Schooling. To test a hypothesis that schooling has no effect on earnings, you will use a t test.

Consider the following least squares specification between test scores and the student-teacher ratio: Test Score^ = 557.8 + 36.42 ln (Income). According to this equation, a 1% increase income is associated with an increase in test scores of:

Assume an omitted variable which is in the error term of a population regression model is positively correlated with one of the independent variables in the model. An estimate of a slope coefficient from a regression where the omitted variable is not included __________ the true value of slope parameter.

Suppose your population regression model has three independent variables. You want to test whether first two independent variables have any effects on the dependent variable. The test statistics is ______ and _______.

Consider the following multiple regression models A) to D) below. DFemale = 1 if the individual is a female, and is zero otherwise; DMale is a binary variable which takes on the value one if the individual is male, and is zero otherwise; DMarried is a binary variable which equals one for married individuals and is zero otherwise, and DSingle is (1-DMarried). Regressing weekly earnings (Earn) on a set of explanatory variables, you will experience perfect multicollinearity in the following cases unless:
