The population standard deviation for the height of college basketball players is 3 inches. If we want to estimate a 99% confidence interval for the population mean height of these players with a 0.5 margin of error, how many randomly selected players must be surveyed? (Round up your answer to nearest whole number) Answer:
Added by Donald C.
Step 1
Since the confidence level is 99%, the alpha level is 1 - 0.99 = 0.01. Look up the z-value for a 0.01 alpha level in a standard normal distribution table, which is approximately 2.576. Show more…

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