The variance is: 3.8
The variance is 10.
(1/6) + (4/6) + (4/8) = (5/6) + (4/8) = (5/6) + (3/6) = 8/6 = 4/3 = 1 and 1/3
7 + 4 + 9 + 8 + 2 = 30 So mean = 30/5 = 6 72 + 42 + 92 + 82 + 22 = 214 So variance = 214/5 - 62 = 42.8 - 36 = 6.8
3/4 - 1/8 = 6/8 - 1/8 = (6 - 1) / 8 = 5/8
Variance = 2.87 (approx).

5.142857143 is the mean.12.43956044 is the variance.3.526976104 is the standard deviation.
sum of scores: 24 mean of scores : 24/4 = 6 squared deviations from the mean: 9, 4,4,9 sum of these: 26 sample variance: 26/4 = 6.5
The answer is: -1-8+4-(-6) = 1
-1-8+4-(-6?
(1/6) + (4/6) + (4/8) = (5/6) + (4/8) = (5/6) + (3/6) = 8/6 = 4/3 = 1 and 1/3
7 + 4 + 9 + 8 + 2 = 30 So mean = 30/5 = 6 72 + 42 + 92 + 82 + 22 = 214 So variance = 214/5 - 62 = 42.8 - 36 = 6.8
(6 1/8) / (1 1/6) = (49/8) / (7/6) = (49/8) * (6/7) = (21/4) = 5 1/4
8 / (6-2+4) = 8/8 = 1/1 = 1
