Marisa has a bag of 40 crayons: 5 blue, 9 orange, 6 yellow, 8 purple and 12 brown. She selects 15 at random.
When she does she gets 2 that are brown. How does this result compare with the results that would be expected based
on probability? Is it: MORE, LESS, THE SAME, or YOU CAN'T TELL?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
