Oct. 8th, 2009 04:34 pmPractice problem my math teacher gave us:
107.Ron thinks he's kind of a big deal and decides to challenge Veronica to an
Anchorperson Aptitude Test (AAT). The average anchorperson scores 100 points (out of
200 possible points), with a standard deviation of 4.5 points. Brick, the newsroom's
shuttle diplomat, gets both parties to agree that being a "big deal" would require an
anchorperson's score to beat 97.5% of the other scores. Ron scores 111 and Veronica
scores 117. Assuming AAT scores are normally distributed, which statement is true?
a) Only Ron is a Big Deal.
b) Both Veronica and Ron are a Big Deal.
c) Only Veronica is a Big Deal.
d) Neither Veronica nor Ron are a Big Deal.
Oh, the little things in life.
