The Frequency Distribution Shows the Ages for a Sample of 100

question 35

Short Answer

The frequency distribution shows the ages for a sample of 100 employees. Find the expected frequencies for
each class to determine if the employee ages are normally distributed. $$\begin{array} { l c } \hline \text { Class boundaries } & \text { Frequency, f } \\\hline 29.5 - 39.5 & 14 \\39.5 - 49.5 & 29 \\49.5 - 59.5 & 31 \\59.5 - 69.5 & 18 \\69.5 - 79.5 & 8 \\\hline\end{array}$$
