Question: The standard deviation of a sample proportion p gets smaller as the sample size n increases. If the population proportion is p =0.51, how large

The standard deviation of a sample proportionpgets smaller as the sample sizenincreases. If the population proportion isp=0.51, how large a sample is needed to reduce the standard deviation ofpto=0.004?(The689599.7rule then says that about 95% of all samples will havepwithin 0.01 of the truep. Round your answer to up to the next whole number.)
