Answer:
The answer is 62 and 86
Explanation:
Mean
(50 + 70 + 58 + 62 + 66 + 53 + 76) ÷ 7
435/7 = 62.1 ≈ 62
Variance
(50 - 62)² + (70 - 62)² + (58 - 62)² + (62 - 62)² + (66 - 62)² + (53 - 62)² + (76 - 62)²
(144 + 64 + 16 + 0 + 16 + 81 + 196)/(7 - 1)
517/6 = 86
Thus, The mean of the given data is 62 and Variance is 86
