Exercise 5

Avg difficulty 3.0

GRE scores, Part II. In Exercise 4.3 we saw two distributions for GRE scores: N(μ=151,σ=7)N(\mu=151,\sigma=7) for the verbal part of the exam and N(μ=153,σ=7.67)N(\mu=153,\sigma=7.67) for the quantitative part. Use this information to compute each of the following:

  1. The score of a student who scored in the 80th80^{th} percentile on the Quantitative Reasoning section.

  2. The score of a student who scored worse than 70% of the test takers in the Verbal Reasoning section.
