Which of the following statements is true with respect to a simple linear regression model? a. The percent of variation in the dependent variable that is explained by the regression model is equal to the square of the correlation coefficient between the x and y variables b. If the correlation coefficient between the x and y variables is negative, the sign on the regression slope coefficient will also be negative c. If the correlation between the dependent and the independent variable is determined to be significant, the regression model for y given x will also be significant d. All of the above are true A large retail company gives an employment screening test to all prospective employees. If a prospective employee receives a report saying that she scored at the 40th percentile: a. she scored above the median b. she scored better than 40 percent of people who took the test c. she scored in the top 40 percent of people who took the test d. her z score was a 40 Which of the following statements is true with respect to a simple linear regression model? a.
