Question

The Graduate Record Examination (GRE) is a test require for admission to many U.S graduate schools. Students' scored on the quantitative portion of the GRE follow a normal distribution with mean 150 and standard deviation 8.8. A graduate school requires that sudents score above 160 to be admitted

1. Determine the combined GRE scores that make up the middle 95% of all scores?

Use the standard normal distribution to determine the following:

2.) 68% of the scores lie between what two values

3.) 95% of the scores lie between what two values

4.) 99% of the scores lie between what two values

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...

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....

The test scores for the analytical writing section of the
Graduate Record Examination can be approximated by a normal
distribution with a mean of 155.69 and a standard deviation of
5.05.
a) What is the maximum score that can be in the bottom 11.4% of
Scores?
b) Between what two values does the middle 74% lie?
c) What is the minimum score that can be in the top 4.5%

Most graduate schools of business require applicants for
admission to take the Graduate Management Admission Council’s GMAT
examination. Scores on the GMAT are roughly normally distributed
with a mean of 527 and a standard deviation of 112.
If a prestigious business school will only take those students
who score in the top 5%, what score would you need to have to be
accepted?

Examination exam scored 640 on the Verbal Reasoning section and 740
on the Quantitative Reasoning section. The mean score for Verbal
Reasoning section was 461 with a standard deviation of 107, and the
mean score for the Quantitative Reasoning was 450 with a standard
deviation of 147. Suppose that both distributions are nearly
normal. Round calculated answers to 4 decimal places unless
directed otherwise.
