Below is a histogram representing the distribution of ages in a certain population. Each bar represents the number of individuals within a specific age group.
Does the display depict a normal distribution? Why or why not? What should be the expected shape of the histogram for a typical normal distribution?

• A. Yes, the histogram represents a normal distribution because it is symmetric and bell-shaped.
• B. No, the histogram does not represent a normal distribution because it lacks a clear peak and symmetry. A normal distribution should be unimodal and bell-shaped.
• C. No, the histogram does not represent a normal distribution because it is skewed to the right. A normal distribution should be approximately symmetric around the mean.
• D. Yes, the histogram represents a normal distribution because the frequencies are evenly distributed across all age groups.

Answer: (B)
