First, find the sample variance s. Recall the computation formula for sample variance s' 2 %3D where x is a value of the data n - 1 set and n is the number of data values. We know that x = 111 and x = 2,665. There are five values %3D in the data set 14, 16, 24, 26, 31, so n = 5 . Substitute these values into the formula to calculate the sample variance. s2 = n - 1 111 2,665 - 5 - 1 2,665 492.84 4. 2172.16 543.04
