WebJust as we needed to have a decent estimate, \(s^2\), of the population variance when calculating the sample size necessary for estimating a population mean \(\mu\), we need to have a good estimate, \(\hat{p}\), of the population proportion when calculating the sample size necessary for estimating a population proportion \(p\). WebMay 1, 2024 · Point Estimates. We start with a point estimate. This is a single value computed from the sample data that is used to estimate the population parameter of … Webthe point estimate should be in the middle of the two bounds, or their average, which is 0.380. If there are 1200 individuals, and 0.38 have a characteristic, that would be 456 of them The margin of error: find the SE, which would be sqrt (0.38*0.62/1200) or 0.0140 Typically 95% is considered the usual confidence interval where z is 1.96 proxy.newproxyinstance 源码
