![SOLVED: Find the minimum sample size needed to be 99% confident that the sample's standard deviation is within 20% of the population's standard deviation. SOLVED: Find the minimum sample size needed to be 99% confident that the sample's standard deviation is within 20% of the population's standard deviation.](https://cdn.numerade.com/ask_previews/408855f5-e282-4f1e-9925-8f708bb8ee18_large.jpg)
