1. Assume that you plan on estimating the following regression kids 2.28-0.98educu where kids is number of kids in the family, educ is years of education, and u is the unobserved error. (a) (10 points) What is the interpretation of the intercept? (b) (10 points) What is the interpretation of the coefficient on educ?

Let kids denote the number of children born to a woman, and let educ denote years of education for the woman. A simple model relating fertility to years of education is 3. where ui is the unobserved error. a. What kinds of factors are contained in u? Are these likely to be correlated with the level of education? Do you expect the sign of the slope parameter to be positive or negative? Why? b.

11. Suppose you are interested in estimating the effect of hours spent in an SAT preparation course (hours) on total SAT score (sat). The population is all college-bound high school seniors for a particular year. (i) Suppose you are given a grant to run a controlled experiment. Explain how you would structure the experiment in order to estimate the causal effect of hours on sat. (ii) Consider the more realistic case where students choose how much time to spend in...

QUESTION 1 Consider the following OLS regression line (or sample regression function): wage =-2.10+ 0.50 educ (1), where wage is hourly wage, measured in dollars, and educ years of formal education. According to (1), a person with no education has a predicted hourly wage of [wagehat] dollars.

QUESTION 2 In multiple linear regression analysis, the number of independent variables should be as large as possible. more than 5. guided by economic theory. enough to guarantee that statistical significance is achieved. QUESTION 3 Omitted variable bias occurs when always occurs when performing simple linear regression analysis. independent variables that should be included in the analysis are not included and those independent variables are related to the variables in the regression model. independent variables that should not be included...
