In the regression model Yi = β0 + β1Xi + β2Di + β3(Xi × Di) + ui, where X is a continuous variable and D is a binary variable, β3:

You will use the data in the table below to answer the next three (3) questions. Each question is worth 10 points.   Observational Unit X Y 1 6 3 2 8 4 3 16 8 4 5 5 5 15 10   Using the data described in the table above, estimate the value of the intercept term (

The Least Squares assumptions for causal inference are:

A 95% confidence set for two or more coefficients is a set that contains:

You extract approximately 5,000 observations from the Current Population Survey (CPS) and estimate the following regression function: = 3.32 — 0.45Age, R2= 0.02, SER = 8.66         (1.00)   (0.04)where ahe is average hourly earnings, and Age is the individual’s age. Given the specification, your 95% confidence interval for the effect of changing age by 5 years is approximately:
