the verbal section of GRE exam for admission into graduate school has a mean of 456 (s=140). Assuming the scores are normally distributed what percent of students will score 600 or higher? (choose range that fits your answer)

Answer 1

Z = (score-mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score. Multiply by 100.
