Final Answer : C, Explanation :  1. Find the mean: (10+19+15+20+21+11)/6 = 162. Calculate each deviation from the mean: (-6, 3, -1, 4, 5, -5)3. Square each deviation: (36, 9, 1, 16, 25, 25)4. Sum the squared deviations: 1025. Divide by the number of data points: 102/6 = 17Therefore, the variance is 17, and the closest choice to 17 is C (22.40).
