Answer: d. percentage of observations on the vertical (y) axis, whereas a frequency histogram indicates counts.
Step-by-step explanation:
A frequency histogram is a graph showing the frequency for the occurrence of an outcome in a data set. A frequency histogram is used to organize data thereby making the data easy to comprehend.
A frequency histogram is a graph that shows how the number of times a particular thing happens, and this is shown in percentages.
Fir an histogram, the horizontal axis is a number line that contains classes of uniform length while the frequency or count is represented on the vertical axis.
The difference between a frequency histogram and a relative frequency histogram is that the relative frequency histogram indicates percentage of observations on the vertical (y) axis, whereas a frequency histogram indicates counts.
Therefore, option d is correct.
