question 23

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 χ² statistic for the independence test?

• A)0.36
• B)0.1296
• C)0.015
