a. Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportions related to the Z scores.
b. Use same table to get Z related to .05 in smaller portion and insert values in above equation to get score.
c. Use table to find proportion and multiply by 200.
