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. (View Pic)

Compare and contrast the two samples. (Select all that apply.)

There are no outliers present.

A typical value is much larger for machine 1 than for machine 2.

Machine 2's sample values have considerably more variation than machine 1's sample values.

The only outlier that exists is from machine 2.

A typical value seems to be about the same for the two machines.

Machine 1's sample values have considerably more variation than does machine 2's sample values.

A typical value is much larger for machine 2 than for machine 1.

The only outlier that exists is from machine 1.

Machine 1 and machine 2's sample values have about the same amount of variation.
