So I guess we got lucky. n/a: homework not graded, but credit given. To compute the homework average, the lowest graded score was dropped, and the remaining graded scores were averaged. ?: For three students, the grade on homework #9 was lost due to a recordkeeping snafu. In this case the homework average was an interval rather than a number. However in all three cases, it turned out that the course grade did not depend on the grade on HW#9.
