Given the following work sampling data, based upon 100 random observations of a particular worker: $$\begin{array} { l c }
\text { Activity } & \text { Times Observed } \
\hline \text { A } & 20 \
\text { B } & 50 \
\text { C } & 10 \
\text { Others } & 20
\end{array}$$ For a confidence level of 95.44 percent and a maximum error of .04, what should be the sample size for estimating the proportion of time spent performing activity B?
