Problem

In the context of part lengths, compare the spreads of the \(\text{two}~\text{distributions}\): machine A values tightly clustered, machine B values spread across the full display.

The actual statistical distribution or paired displays needed to answer the prompt, without the conclusion.

Machine A has greater variability in part lengths because its values are tightly clustered, which means the lengths vary more from one another.

Machine B has greater variability in part lengths because its values are spread across the full display, while machine A’s values are tightly clustered.

Machine B has less variability in part lengths because values spread across the full display are more evenly placed, so the lengths are more consistent.

Both machines have the same variability in part lengths because each distribution shows part lengths on the same display.
