1. **Problem:** Decide whether each distribution (a to f) is approximately bell-shaped based on the histogram descriptions. 2. **Recall:** A bell-shaped distribution is symmetric, unimodal (one peak), and resembles the normal distribution curve. 3. **Analysis:** - a. Bars form a symmetric bell-shaped curve with a central peak. **Bell-shaped: Yes** - b. Smaller but symmetric bell-shaped distribution. **Bell-shaped: Yes** - c. Frequencies rise and fall irregularly, not symmetric. **Bell-shaped: No** - d. Frequencies jump irregularly, no bell shape. **Bell-shaped: No** - e. Two distinct peaks (bimodal). **Bell-shaped: No** - f. Skewed distribution with peak near center but trailing right. **Bell-shaped: No** **Final answers:** a: Yes, b: Yes, c: No, d: No, e: No, f: No
