ANSWER:
Step 1 of 4
A frequency histogram typically consists of data grouped into classes or intervals, along with the frequency (or count) of data points that fall within each class.
a) The number of classes is the same as the number of bars in the histogram.
The given frequency histogram contains 7 bars, so there are 7 classes.
Thus, the number of classes is 7.
