**Courtney**, Monday, April 1, 2013 at 12:00pm1 should be ¼ so it should be drawn 25 times

2 should be ½ so it should be drawn 50 times

5 should be ¼ so it should be drawn 25 times

Avg=10/4=2.5

S2=(2.25+.25+.25+6.25)/4=9/4=.25 so S=1.5

ES=100(2.5)=250

SE=√100 (1.5)=15

A. number of 2's

B. Sum of the draws (270-250=20 and 20/15=1.33)
