Times (s) taken by 150 athletes in a 110 m hurdle race:
| Class | 13.8–14 | 14–14.2 | 14.2–14.4 | 14.4–14.6 | 14.6–14.8 | 14.8–15 |
|---|---|---|---|---|---|---|
| Frequency | 2 | 4 | 5 | 71 | 48 | 20 |
The number who finished in less than 14.6 s is
11
71
82
130
Step 1: Look carefully at the classes (time intervals). We want the number of athletes who finished the race in less than 14.6 seconds.
Step 2: The class intervals below 14.6 are:
Step 3: Add all these frequencies:
\(2 + 4 + 5 + 71 = 82\)
Step 4: Therefore, the total number of athletes who finished in less than 14.6 seconds is 82.
So, the correct answer is Option C (82).
