Question 12 4 / 4 points If the Durbin-Watson statistic has a value close to 0, which assumption is violated? In other words, which assumption is the Durbin-Watson statistic checking to see is violated?
Question 13 4 / 4 points The standard error of the estimate is a measure of total variation of the Y variable. the variation around the sample regression line. explained variation.
the variation of the X variable. Question 14 4 / 4 points The coefficient of determination ( r 2 ) tells us
Question 15 4 / 4 points True or False: The Regression Sum of Squares (SSR) can never be greater than the Total Sum of Squares (SST). True False
Question 16 4 / 4 points True or False: The coefficient of determination represents the ratio of SSR to SST.
Question 17 4 / 4 points In a multiple regression problem involving two independent variables, if b 1 is computed to be +2.0, it means that the relationship between X 1 and Y is significant. the estimated average of Y increases by 2 units for each increase of 1 unit of X 1 , holding constant. the estimated average of Y increases by 2 units for each increase of 1 unit of X 1 , without regard to X 2 X 2 .
