Choose whether range or IQR is the better spread measure for data where the absolute difference between the minimum and maximum values is explicitly needed.
Using a hint is okay. It just tells the trainer to give you a little more review.

Walkthrough
Full solution stays hidden until you ask for it.
1. Determine whether outliers are present or full spread is needed.
2. Use IQR for resistant middle-half spread.
3. Use range for total minimum-to-maximum spread.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using IQR when the question explicitly asks for total spread.
