2. 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 standard deviation 8.8. (Source: http://www.ets.org/.) Suppose a random sample of 10 students took the test, and their scores are given below: 152, 126, 146, 149, 152, 164, 139, 134, 145, 136. Test the claim that the mean verbal reasoning score is different from 150 using the P-value approach at...

Suppose that Rachel studied for the Graduate Management Admission Test (GMAT) using a well-known preparation class and was thrilled to receive a total score of 770. Her friend Eric, however, thinks she would have scored just as well without the class. To test the efficacy of the class, they obtain a small but random sample of 19 test results from other students using the same class. This sample's average is 568.56 with a standard deviation of 116.72. In comparison, the...

Suppose that in a certain year, it was reported that the variance
in GMAT scores was 14,640. add a recent summit, a group of
economics professor's met to discuss the GMAT performance of
undergraduate students majoring in economics. Some expect it to be
variability in GMAT scores achieved by the undergraduate economic
students to be greater than the variability in GMAT scores of the
general population of GMAT takers. However, others took the
opposite view. Suppose the following are GMAT...

The College Board provided comparisons of Scholastic Aptitude Test (SAT) scores based on the highest level of education attained by the test taker's parents. A research hypothesis was that students whose parents had attained a higher level of education would on average score higher on the SAT. The overall mean SAT math score was 514. SAT math scores for independent samples of students follow. The first sample shows the SAT math test scores for students whose parents are college graduates...
