1. Write down the responses: 
   $$
   18,\, 14,\, 15,\, 4,\, 7,\, 9,\, 6
   $$
   
2. Compute the sum of the responses:
   $$
   18 + 14 = 32\
   32 + 15 = 47\
   47 + 4 = 51\
   51 + 7 = 58\
   58 + 9 = 67\
   67 + 6 = 73
   $$
   
3. The mean (average) is given by:
   $$
   \text{Mean} = \frac{\text{Total hours}}{\text{Number of students}} = \frac{73}{7} \approx 10.42857
   $$
   
4. Rounding to the nearest tenth:
   $$
   \text{Mean} \approx 10.4 \text{ hours}
   $$
The mean number of hours is approximately 10.4 hours.
