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.". The second question is similar. Free functions calculator - explore function domain, range, intercepts, extreme points and asymptotes step-by-step Variance measures dispersion of data from the mean.
