This tells us that \(\bar X\) is also centered at \(\mu \) but its dispersion is less than that for each individual It uses the Good-Turing and Decide math problems You can measure the . However, sampling statistics can be used to calculate what are called confidence intervals, which are an indication of how close the estimate p is to the true value p. The uncertainty in a given random sample (namely that is expected that the proportion estimate, p, is a good, but not perfect, approximation for the true proportion p) can be summarized by saying that the estimate p is normally distributed with mean p and variance p(1-p)/n. Your email address will not be published. Step 1: Identify the variance of the population.
