Using the given data sets, construct a boxplot for both groups and compare the two data sets. The table below presents resting heart rates (in beats per minute) for $10$ athletes and $10$ non-athletes.

• A. Both groups have the same median, but non-athletes have more outliers.
• B. The range of resting heart rates is the same for both groups.
• C. Non-athletes have a lower median resting heart rate and a smaller interquartile range.
• D. Athletes generally have lower resting heart rates and less variability compared to non-athletes.
