Use the frequency table that you constructed in question number 3 to find the percentile rank.

What is the percentile rank of Age of 45. Round up to two numbers after the decimal point in percentile rank.

$\begin{array}{|cccc|}\hline \text{Age}& \text{Frequency = f}& \text{relative Frequency = rf}& \text{Cumulative frequency =>cf}\\ 74-93& 5& (5/27)=0.185& 27\\ 54-73& 7& (7/27)=0.259& 22\\ 34-53& 5& (5/27)=0.185& 15\\ 14-33& 10& (10/27)=0.370& 10\\ \text{Total}& 27\\ \hline\end{array}$
