D) depends on the population size
E) depends on the frequency

Question

The total area of the bars in a histogram represents the proportion (or percentage) of data that falls within each interval. The width of each bar represents the interval size, and the height of each bar represents the frequency (or relative frequency) of data that falls within that interval. Therefore, the total area of the bars depends on the width of each bar, as this determines the total amount of space (area) needed to represent the data in the histogram. The other factors listed (sample size, number of bars, population size, and frequency) may affect the shape and distribution of the histogram, but they do not directly impact the total area of the bars.
