the options are kind of confusing. i can tell you what i see going on here when i look at the graph.
the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
