1. **Problem Statement:** Use the histogram to answer the following questions about the number of cars sold in a week. 2. **Most Frequent Number of Cars Sold:** The histogram shows the highest bar at 4 cars sold. 3. **Weeks with 2 Cars Sold:** The frequency for 2 cars sold is 9 weeks. 4. **Relative Frequency of 3 Cars Sold:** Relative frequency is calculated as: $$\text{Relative Frequency} = \frac{\text{Frequency of 3 cars}}{\text{Total weeks}} \times 100\%$$ Given relative frequency is 15.69%, so the frequency of 3 cars sold corresponds to this percentage. 5. **Shape of Distribution:** The histogram is skewed right, meaning the tail on the right side is longer or fatter. 6. **Stem and Leaf Plot:** Given data for cholesterol levels is organized into stems (tens) and leaves (units): $$\begin{array}{l} 2 | 8 \\ 3 | 682589 \\ 4 | 6825845628 \\ 5 | 66313861145022 \\ 6 | 902306 \\ 7 | 030 \end{array}$$ 7. **Shape of Cholesterol Distribution:** The distribution is symmetric or shows little skew. 8. **Mean vs Median:** The handwritten answer is missing, but typically for symmetric distributions, mean and median are close or equal. **Final answers:** - Most frequent number of cars sold: $4$ - Weeks with 2 cars sold: $9$ - Relative frequency of 3 cars sold: $15.69\%$ - Shape of car sales distribution: Skewed right - Shape of cholesterol distribution: Symmetric / Little skew - Mean and median comparison: Mean approximately equals median
