Question 1070047: On the SAT, the average Writing score is 473 points and the average Mathematics score is 521 points. The standard deviation is 81 points on each part of the test. Now suppose 36 test takers are selected.
1. 96% of the time the sample average Writing score should be less than what? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! t(df=35)0.96=1.80
for writing, it should be less than 473+(1.8*81/sqrt(36))
473+24.3=497.3 for a sample this size
