1. **Stating the problem:** We want to analyze the distribution of hours of sleep per night based on the responses from a group of people. 2. **Given data:** - 2 people said 0 hours (no sleep) - 1 person said 0-3 hours - 24 people said 4-6 hours - 18 people said 7-9 hours - 5 people said 10+ hours 3. **Interpreting the data:** We can summarize the number of people in each sleep category. 4. **Calculating total number of people:** $$2 + 1 + 24 + 18 + 5 = 50$$ 5. **Finding the percentage of people in each category:** - 0 hours: $$\frac{2}{50} \times 100 = 4\%$$ - 0-3 hours: $$\frac{1}{50} \times 100 = 2\%$$ - 4-6 hours: $$\frac{24}{50} \times 100 = 48\%$$ - 7-9 hours: $$\frac{18}{50} \times 100 = 36\%$$ - 10+ hours: $$\frac{5}{50} \times 100 = 10\%$$ 6. **Summary:** Most people (48%) sleep between 4-6 hours, followed by 36% sleeping 7-9 hours. A small percentage sleep 0 or very few hours, and 10% sleep 10 or more hours.
