Exercise 14.3 gave the data in the table for scores on the first quiz for ninth-grade students in an introductory-level French course. The instructor grouped the students in the course as follows:
Group 1: Never studied foreign language before, but have good English skills
Group 2: Never studied foreign language before; have poor English skills
Group 3: Studied at least one other foreign language
The table also shows results of using MINITAB to perform the Kruskal-Wallis test.
a. Find the rank associated with each observation, and show how to find the mean rank for Group 1.
b. Report and interpret the P-value for the test.
