3.5 GRE scores, Part II:  In Exercise 3.3 we saw two distributions for GRE scores: N(μ=151,σ=7) for the verbal part of the exam and N(μ=153,σ=7.67) for the quantitative part. Use this information to compute each of the following:
(Keep 2 decimal places.)

a) The score of a student who scored in the 80-th percentile on the Quantitative Reasoning section.
b) The score of a student who scored worse than 60% of the test takers in the Verbal Reasoning section.
