Plzzz explain all question.


Extracted text: Find the INTEGER minimum sample size required to estimate the population proportion p: Margin of error: 0.04; confidence level: 92%; p and ĝ are not known, Answer: Find the INTEGER minimum sample size required to estimate the population proportion p: Margin of error: 0.09; confidence level: 95%; from a prior study, p is known to be 33%. Answer: Find the INTEGER minimum sample size required to estimate the population proportion p: in a certain population, body weights are normally distributed with a mean of 152 pounds and a standard deviation of 26 pounds. How many people must be surveyed if we want to estimate the percentage p who weigh more than 180 pounds? Assume that we want 97.5% confidence that the error is no more than 1.7 percentage points; no prior results on estimating p are available.
