1. The problem is to analyze the sales frequencies of different types of nonfiction books: Biography, Cooking, Travel, History, and Science. 2. We are given the frequencies: Biography = 14, Cooking = 11, Travel = 7, History = 10, Science = 8. 3. To understand the distribution, we can calculate the total sales and the relative frequency (percentage) of each category. 4. Total sales = $14 + 11 + 7 + 10 + 8 = 50$. 5. Relative frequency for each category is calculated by dividing the category frequency by the total sales: $$\text{Relative frequency} = \frac{\text{Category frequency}}{\text{Total sales}}$$ 6. Calculations: - Biography: $\frac{14}{50} = 0.28$ or 28%. - Cooking: $\frac{11}{50} = 0.22$ or 22%. - Travel: $\frac{7}{50} = 0.14$ or 14%. - History: $\frac{10}{50} = 0.20$ or 20%. - Science: $\frac{8}{50} = 0.16$ or 16%. 7. This shows Biography books have the highest sales frequency, followed by Cooking, History, Science, and Travel. This analysis helps understand which nonfiction book types are most popular based on sales frequency.
