QUESTION 19
Suppose we have a regression line where the intercept is a
=0.24 and the slope is 3 = 0.87. Our variable of interest is x.
Suppose the standard errors for the intercept 0.02 and the slope is 0.07. What is the margin of error for the intercept? (This is in your
textbookl)
QUESTION 20
Suppose we have a regression line where the intercept is a = 0.24 and the slope is
=0.87. Our variable of interest is x
Suppose the standard errors for the intercept 0.02 and the slope is 0.07. What is the lower estimate for a one year increase in the x
variable according to the margin of error? (This is in your textbook!)
QUESTION 21
Suppose we have a regression line where the intercept is a= 0.24 and the slope is 3= 0.87. Our variable of interest is x.
Suppose the standard errors for the intercept 0.02 and the slope is 0.07. What is the upper estimate for a one unit increase in the x
variable according to the margin of error?
