Question:
When using histograms to compare two data sets, it is sometimes difficult to make comparisons by looking back and forth between the two histograms. A back-to-back relative frequency histogram uses a format that makes the comparison much easier.

Complete the back-to-back relative frequency histograms shown below by using the data from Table 2-8 on page 51. Then use the result to compare the two data sets.
