The range for a set of data is estimated to be $36.$ $$\begin{array}{l}{\text { a. What is the planning value for the population standard deviation? }} \\ {\text { b. } A t 95 \% \text { confidence, how large a sample would provide a margin of error of } 3 ?} \\ {\text { c. At } 95 \% \text { confidence, how large a sample would provide a margin of error of } 2 ?}\end{array}$$
