What are the mean, variance, and standard deviation of these values? Round to the nearest tenth. 92, 97, 53, 90, 95, 98
Mean: (92 + 97 + 53 + 90 + 95 + 98) / 6 = 85.8
Variance: [(92-85.8)^2 + (97-85.8)^2 + (53-85.8)^2 + (90-85.8)^2 + (95-85.8)^2 + (98-85.8)^2] / 6 = 277.6
Standard deviation: √(277.6) ≈ 16.7
Mean: 85.8
Variance: 277.6
Standard deviation: 16.7
