Question
Multiple Choice (24 points) 1) When the estimated slope coefficient in the simple regression model, P1, is zero, A) R2-Y B) R2-0. C) 0 (SSRITSS) 2) The following are all least squares assumptions with the exception of A) The conditional distribution of ui given X has a mean of zero. B) (X?, Y), i-| , , n are independently and identically distributed. C) Large outliers are unlikely D) The explanatory variable in regression model is normally distributed. 3) To decide whether the slope coefficient indicates a "large" effect of X on Y, you look at the A) size of the slope coefficient B) regression R2 C) economic importance implied by the slope coefficient D) value of the intercept 4) The OLS residuals, "i, are sample counterparts of the population A) regression function slope B) errors C) regression function's predicted values D) regression function intercept 5) For simple linear regressions, the sample regression line estimated by OLS A) will always have a slope smaller than the intercept. B) is exactly the same as the population regression line. C) cannot have a slope of zero. D) will always run through the point (X, Y).Explanation / Answer
When the estimated slope coefficient in the simple regression model is zero,
then R2 = 0
