For the population dataset 99, 100, 100, 100, and 101, find the Variance. The mean value is 100 for this dataset. Some basic calculation is done below for you but you will have to take it further to calculate the variance. (x u) Dept. A 99 100 100 100 101 99 - 100 = -1 100 - 100 = 0 100 - 100 = 0 100 - 100 = 0 101 - 100 = 1 0 Select one: O a. Variance is 0.40 b. Variance is 0.60 O c. Variance is 0.632 d. Variance is 0.20
