1. The problem is to analyze the nonfiction book sales data given in categories and their frequencies: Biography (14), Cooking (11), Travel (7), History (10), and Science (8). 2. We can represent this data as a frequency distribution table or a bar graph to visualize the sales. 3. To find the total number of nonfiction books sold, sum all frequencies: $$14 + 11 + 7 + 10 + 8 = 50$$ 4. To find the relative frequency (proportion) of each category, divide each frequency by the total sales: - Biography: $$\frac{14}{50} = 0.28$$ - Cooking: $$\frac{11}{50} = 0.22$$ - Travel: $$\frac{7}{50} = 0.14$$ - History: $$\frac{10}{50} = 0.20$$ - Science: $$\frac{8}{50} = 0.16$$ 5. These relative frequencies can help understand the share of each category in total sales. 6. If needed, we can plot these frequencies or relative frequencies to visualize the data better.
