Problem 19BSC

Back­-to­-Back Relative Frequency Histograms 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 back­to­back relative frequency histogram has a format that makes the comparison much easier. Instead of frequencies, we should use relative frequencies (percentages or proportions) so that the comparisons are not difficult when there are different sample sizes. Use the relative frequency distributions of the ages of Oscar­-winning actresses and actors from Exercise 15 in Section 2­2, and complete the back­to­back relative frequency histograms shown   below. Then use the result to compare the two data sets.

Step-by-Step Solution:
Step 1 of 3

Solution 19BSC

The magnitudes appear approximately to be normal. The frequency start 5, and then increase to frequency 15, then increase to 19, then decrease to a frequency 7 and then decrease to two.
