Consider the following regression output where the dependent variable is test scores and the two explanatory variables are the student-teacher ratio and the percent of English learners: = 698.9 – 1.10×STR – 0.650×PctEL. You are told that the t-statistic on the student-teacher ratio coefficient is -2.56. The standard error for this coefficient estimate is (round to two decimal places):

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:

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:
