Because the question refers to “individual machine operators,” refer to the individual data points rather than the curve marked \(“Average.”\) A defective part rate of 4.2% equates to \(\frac{4.2}{100}× 1,000 = 42\) defective parts per 1,000. The chart has only two data points at approximately 42 defective parts per 1,000. The less experienced of these two machine operators had just under 8,000 hours of experience.
