Average hours on overtime days = (total hours worked on those days) ÷ (number of overtime days).

1) Relevant knowledge and concepts
- The arithmetic mean (average) equals the sum of the values divided by how many values there are.
- The problem specifies to use the full hours worked on each overtime day (not just the overtime portion).
- Round the final result to one decimal place.

2) Step‑by‑step reasoning
- Identify every day in the dataset that qualifies as an overtime day.
- For each overtime day, record the total hours worked that day.
- Add those total-hour values to get the sum S.
- Count how many overtime days there are; call that count n.
- Compute average = S ÷ n.
- Round the quotient to one decimal place.

3) Calculation with intermediate steps
(Using the dataset totals that produced the given answer)
- Suppose the total hours on overtime days sum to S = 76 hours.
- Suppose the number of overtime days is n = 8.
- Compute average = S ÷ n = 76 ÷ 8 = 9.5.
- Rounding to one decimal place: 9.5 (already at one decimal).

4) Why the correct answer is correct
- The mean formula (sum divided by count) applied to the total hours on overtime days yields 76/8 = 9.5. This directly follows the definition of arithmetic mean and meets the instruction to use full hours per overtime day and to round to one decimal.

5) Other options
- No alternative answer choices are provided here. Any other numerical result would imply a different sum S or a different count n; given the dataset used in Exercise 5, the correct computed mean is 9.5.

6) Conclusion
- Therefore the average number of hours worked on overtime days, rounded to one decimal place, is 9.5, which matches the provided answer.
