Question

Explanation:

• Option A: The dot plot is not symmetric as the left side (around 5 minutes) has a single dot while the right has more concentrated dots.
• Option B: Range is max - min = 45 - 5 = 40, not 25.
• Option C: The dot at 5 minutes is far from the main cluster (20 - 45 minutes), so it is an outlier.
• Option D: The cluster is from 20 - 45 minutes, not just 25 - 35.

Answer:

C. The distribution appears to have an outlier.
