Question

The Graduate Record Examination (GRE) is a standardized test commonly taken by graduate school applicants in the United States. The total score is comprised of three compo- nents: Quantitative Reasoning, Verbal Reasoning, and Analytical Writing. The first two components are scored from 130 - 170. The mean score for Verbal Reasoning section for all test takers was 151 with a standard deviation of 7, and the mean score for the Quantitative Reasoning was 153 with a standard deviation of 7.67. Suppose that both distributions are nearly normal. (a) A student scores 160 on the Verbal Reasoning section and 157 on the Quantitative Reasoning section. Relative to the scores of other students, which section did the student perform better on? (b) Calculate the student’s percentile scores for the two sections. What percent of test takers per- formed better on the Verbal Reasoning section? (c) Computethescoreofastudentwhoscoredinthe80thpercentileontheQuantitativeReasoning section. (d) Compute the score of a student who scored worse than 70% of the test takers on the Verbal Reasoning section.

Answer #1

Amanda took the Graduate Record Examination (GRE), and scored
160 in verbal reasoning and 157 in quantitative reasoning. The mean
score for verbal reasoning was 151 with a standard deviation of 7,
compared with mean µ = 153 and σ = 7.67 for quantitative reasoning.
Assume that both distributions are normal.
(a) What were Amanda’s Z-scores on these exam sections? Mark
these scores on a standard normal distribution curve.
(b) Which section did she do better on, relative to other...
