Above is a scatterplot with one point labeled X. Suppose you find the least squares regression line. Which of the following is a correct statement? A. X has the largest residual, in absolute value, of any point on the scatterplot. B. X is an influential point. C. The residual plot will show a curved pattern. D. The association between the x and y variables is very weak. E. If the point X were removed, the correlation would be 1.

QUESTION 18: A mathematical model that describes the linear relationship between a dependent variable (y) and values of an independent variable (x), along with a random error term (e), is called: A. an estimated regression equation/model B. a probabilistic model C. a deterministic model D. the least squares regression line QUESTION 19: In linear regression, another name for the independent variables (X) is: A. dependent variables B. explained variables C. predicted variables D. explanatory variables QUESTION 20: In a multiple regression analysis involving 15 independent variables (k) and 200 observations (n), SSR = 560 and SSE = 240. The proportion of the total variation in the dependent variable (y) that is explained by the proportion of the variation in the independent variables (x's) is thus: A. 0.572 B. 0.700 C. 0.300 D. 0.438 QUESTION 21: If the coefficient of determination (R^2) is equal to 0.20, then the percentage of the total variation in the dependent variable (y) that is NOT explained by the variation in the independent variables (x's) is: A. 0.80 B. 0.80% C. 0.20% D. 20%
