Finally, here is a real life word word problem. During the Fall of
2006, in Exam 2 of Math 1010-1 (our class), 199 people took the
exam and received an average score of 62%. 84
people did not pick up their exam, presumably because they did not
attend class on the day the exam was handed back. Those people had an
average score of 58%. Thus the people who did pick
up their exams, and presumably did attend class, had an average score
of
%. (Round your answer to the nearest
integer.)
Of course, assuming attendance on a particular day is correlated with
attendance in general, the moral of the story is that it pays to come
to class. I would have liked to see this case made more
forcefully, but the above are the actual figures.
