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. (NOTE: Write your answer in number format, with 2 decimal places of precision level; do not write your answer as a fraction. Add a leading minus sign symbol, a leading zero and trailing...

QUESTION 6 For this question, you should load the R library wooldridge, first. This can be done by : library(wooldridge). Then import "cps91" to answer the question. Question : You would like to estimate the marginal effects of age, education, experience on hourly wage. The variables are labeled as age, educ, exper, and hwage respectively. What would be the regression equation you would estimate? Olwage = Bo +Bleduc +Bzexper+Bzage + u; Ohrwage = Be + Bleduc +Bzexper+B3age + u; Ohrwage...

Drop down: zero or nonzero / holds of does not hold.
True or False: Assuming the model is linear in parameters, and
you obtain a random sample of observations with varying values of
education, the simple OLS slope and intercept estimates will be
unbiased.
