WebWhen population proportion cannot be assumed, we can calculate the estimated standard error of the proportion ( sep ) as: sep = sqrt ( p ^ q ^/ n) Since, sample proportions based in this population will be approximately normally distributed, we know that about 95% of such estimates will be within ± (2) ( SEP) of the population's proportion. WebIn the context probability & statistics for data analysis, the estimation of standard error (SE) of mean is used in various fields including finance, tele-communication, digital & analog …
