Identify the class width, class midpoints, and class boundaries for the given frequency distribution. Also identify the number of individuals included in the summary. The frequency distributions are based on real data from Appendix B. $$\begin{array}{|c|c|} \hline \begin{array}{c} \text { Age (yr) of Best Actress } \\ \text { When Oscar Was Won } \end{array} & \text { Frequency } \\ \hline 20-29 & 29 \\ \hline 30-39 & 34 \\ \hline 40-49 & 14 \\ \hline 50-59 & 3 \\ \hline 60-69 & 5 \\ \hline 70-79 & 1 \\ \hline 80-89 & 1 \\ \hline \end{array}$$
