    The mean was 67. We gave 6 points for each right answer except on #11, where a right answer was worth 4 points. We gave 2 points for each blank answer, except on #11, where a blank answer was worth 1 point.

    On the error report, your result for #11 will always be reported, because on the answer key I left a blank there. We penciled in a response for you, so a 1 is worth 1 point, a 2 is worth 2 points, a 3 is worth 3 points, a 4 is worth 4 points, and a 5 is worth 0 points.
