6.36. Find the sample size needed to give ,with 95% confidence,  a margin of error with 3% when estimating a proportion.  First ,find the sample size needed if we have no prior knowledge about the population proportion.  Then find the sample size needed If we have reason to believe that p~0.7, finally, find the sample size needed if we assume p~0.9.
