TABLE 12-10 One Criterion Used to Evaluate Employees in the Assembly Section

question 199

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. The quality control department wants to find out whether there is a relationship between years of experience and defect rate. 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, for the cell with 1 to 4 years of training time and a high defect rate, what is the contribution to the overall X² statistic for the independence test?

• A) 0.36
• B) 0.1296
• C) 0.015
• D) 0.0144
