Explanation:

Step1: Identify relevant intervals

We need to consider times greater than 2.5 minutes. So we look at the intervals 3, 3.5, 4, 4.5 on the dot plot.

Step2: Count dots in relevant intervals

• For 3: 0 dots
• For 3.5: 0 dots
• For 4: 1 dot
• For 4.5: 0 dots

Summing these, we get \(0 + 0 + 1 + 0 = 1\).
