The formulas for the mean and variance of sample data are given in the table that follows. In the space below, write the expressions that show the substitution of the values 3, 2, 2, 8, and 2 into the formulas above. In the boxes provided, write the formulas for the population mean and variance. In the boxes provided, find the population mean and variance of a data set consisting of the values 0 and 1. Give an example where sigma(x – x) = 0.
