TABLE 12-4
One Criterion Used to Evaluate Employees in the Assembly

question 92

Multiple Choice

TABLE 12-4
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.
$$\begin{array}{l}\text {\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad Years Since Training Period }\\\begin{array} { r | r r c } &< 1 \text { Year } & 1 - 4 \text { Years } & 5 \text { - 9Years } \\\hline \text { High } & 6 & 9 & 9 \\\text { Defect Rate: Average } & 9 & 19 & 23 \\\text { Low } & 7 & 8 & 10\end{array}\end{array}$$
-Referring to Table 12-4, what is the expected number of employees with 1 to 4 years of training time and a high defect rate?

• A) 8.64
• B) 12.00
• C) 6.67
• D) 6.00
