Question

The Graduate Record Examination (GRE) is a test required for admission to many U.S. graduate schools. Students’ scores on the quantitative portion of the GRE follow a normal distribution with mean 150 and standard deviation 8.8. (Source:www.ets.org). A graduate school requires that students score above 160 to be admitted

6. What is the percentile rank of a student who earns a quantitative GRE score of 142?

7. Historically, Depart of History at NYU has admitted students whose quantitative GRE score is at least at the 61st percentile. (Source: history.fas.nyu.edu/object/admissions.faq.html.) What is the lowest GRE score of the students they admit?

8. Determine the 80th percentile of combined GRE scores.

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

Only need above answers! these is rest of question

- What proportion of combined GRE scores can be expected to be over 160?
- What proportion of combined GRE scores can be expected to be under 160?
- What proportion of combined GRE scores can be expected to be between 155 and 160?
- What is the probability that a randomly selected student will score over 145 points?
- What is the probability that a randomly selected student will score less than 150 points?

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....

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.

Scores on the GRE. A college senior who took
the Graduate Record Examination exam scored 580 on the Verbal
Reasoning section and 730 on the Quantitative Reasoning section.
The mean score for Verbal Reasoning section was 456 with a standard
deviation of 132, and the mean score for the Quantitative Reasoning
was 443 with a standard deviation of 153. Suppose that both
distributions are nearly normal. Round calculated answers to 4
decimal places unless directed otherwise.
