Three admission test preparation programs are being evaluated. Suppose the scores obtained by a sample of 20 people who used the programs provided the following data.

Program
A B C
510 450 600
400 510 630
460 400 590
530 420 460
460 490 560
620 380 640
550 580

Use the Kruskal-Wallis test to determine whether there is a significant difference among the three test preparation programs. Use α = 0.05.

Find the value of the test statistic. (Round your answer to two decimal places.)

Find the p-value. (Round your answer to three decimal places.)

Suppose that Raven 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...

An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second​ time, the students took the​ instructor's course to try to improve their critical reading test scores. At a​ = 0.01, is there enough evidence to support the​ instructor's claim? Complete parts​ (a) through​ (f). number of students:14....

Two teaching methods and their effects on science test scores are being reviewed. A random sample of 11 students, taught in traditional lab sessions, had a mean test score of 78.1 with a standard deviation of 3 . A random sample of 19 students, taught using interactive simulation software, had a mean test score of 84.1 with a standard deviation of 5.9 . Do these results support the claim that the mean science test score is lower for students taught...
