When a common regression line for two groups is used to predict performance, but the individual regressions lines for the groups differ where they cross the y-axis, which one of the following problems may occur? The performance of neither group will be overpredicted. The performance of both groups will be overpredicted The performance of the group whose regression line crosses the y-axis at a lower point will be overpredicted. The performance of the group whose regression line crosses the y-axis at a higher point will be overpredicted
