Question

A company utilizes two different machines to manufacture parts of a certain type. During a single shift, a sample of n = 20 parts produced by each machine is obtained, and the value of a particular critical dimension for each part is determined. The comparative boxplot below is constructed from the resulting data. Compare and contrast the two samples. (Select all that apply.) The median for machine 1 is much larger than the median of machine 2. Machine 1 and machine 2?s sample values have about the same amount of variation. Machine 2?s sample values have considerably more variation than machine 1?s sample values. The only outlier that exists is from machine 1. The median for machine 1 seems to be about the same as the median for machine 2. The median for machine 2 is much larger than the median of machine 1. Machine l?s sample values have considerably more variation than does machine 2?s sample values. The only outlier that exists is from machine 2. There are no outliers present.

Explanation / Answer
