Final answer:
A flat histogram suggests less variability compared to a bell-shaped histogram.
Step-by-step explanation:
The statement is false. If a histogram is flat, it indicates less variability compared to a bell-shaped histogram. A flat histogram suggests that the data points are evenly spread out and have similar frequencies. On the other hand, a bell-shaped histogram indicates a normal distribution with a higher concentration of data around the mean, implying less variability.
