Question 98

Multiple Choice
TABLE 12-10 One criterion used to evaluate employees in the assembly section of a large factory is the number of defective pieces per 1,000 parts produced.

Since the job is repetitious, after the initial training period any improvement due to a learning effect might be offset by a loss of motivation. A defect rate is calculated for each worker in a yearly evaluation. The results for 100 workers are given in the table below. -Referring to Table 12-10, which test would be used to properly analyze the data in this experiment to determine whether there is a relationship between defect rate and years of experience? A) X² test for independence B) X² test for differences among more than two proportions C) Wilcoxon rank sum test for independent populations D) Kruskal-Wallis rank test
