Question: When solving for the sample size needed to compute a 95% confidence interval for a population proportion "p", having a given error bound "B", we choose a value of \(\hat{p}\) that makes:

1. \(\hat{p}(1-\hat{p})\) as small as reasonably possible
2. \(\hat{p}(1-\hat{p})\) as large as reasonably possible
3. \(\hat{p}(1-\hat{p})\) as close to .5 as reasonably possible
4. \(\hat{p}(1-\hat{p})\) as close to .25 as reasonably possible
5. Both B and D are correct
