WebThe standard error (otherwise called as confidence interval) of sample proportion is used to estimate population proportion. If you find the 99% confidence interval (0.45 to 0.66 for example) from a sample proportion, it says that the population proportion is between that interval (0.45 to 0.66). http://rossmanchance.com/ISIapplets.html
