Answer

A right-skewed histogram, left-skewed histogram, bell-shaped histogram and uniform histogram is shown below:

Work Step by Step

The data is right-skewed when the data set values are more toward the right of the histogram. The data is left-skewed when the data set values are more toward the left of the histogram. If the data is normally distributed, that is, both the right and left-side values are mostly equal, then the data will have a bell-shaped histogram. If the data values for each class are almost equal, then its histogram appears to be a uniform histogram. If the data is normally distributed, that is, both the right and left-side values are mostly equal, then the data will have a bell-shaped histogram, which is also known as a symmetric histogram.
