WebInterval Estimate of Population Mean with Unknown Variance. After we found a point estimate of the population mean, we would need a way to quantify its accuracy. Here, we discuss the case where the population variance is not assumed. Let us denote the 100 (1 −α∕2) percentile of the Student t distribution with n− 1 degrees of freedom as ...
