Answer:

D

Step-by-step explanation:

The interquartile range IQR = Q₃ - Q₁ = 13. The most commonly accepted definition of an outlier is any value greater than Q₃ + 1.5 (IQR) = 110.5 or less than Q₁ - 1.5 (IQR) = 58.5. Looking at the minimum and maximum values, we see that there are no outliers on the lower end, and at least one outlier on the upper end.
