The (N-n)/(N-1) term in the finite population equation is referred to as the finite population correction factor, and is necessary because it cannot be assumed that all individuals in a sample are independent. The formula for maximum is: The range of a data set is the difference between the minimum and maximum. 1 1 . The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.".

It uses the Good-Turing and Decide math problems Since any linear combination of normal variables is also normal, the sample mean \(\bar X\) is also normally distributed (assuming that each \(X_i\) is normally distributed). Vo5 Shampoo Discontinued, << have a standard normal distribution. 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. Q: Determine x? Q: The perimeter of a rectangle is 20 feet. C q" Thus, to estimate p in the population, a sample of n individuals could be taken from the population, and the sample proportion, p, calculated for sampled individuals who have brown hair.
