It is easy to decipher the step-by-step calculation of variance from the definition above. 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.". {MX6O`t#_>NH~t1i2HDoF\Tc$ sFi~xrUryWV0 tYA0p N{Ar48X`d ?KJOgs_tD0&%o>N?]. u = 89, sigma = 18, n = 27.
