Explanation:
Detailed explanation-1: -7, 11, 12, 15, 31, 22. Therefore, range of given value 24. Because we have n = 11 samples, we have to divide the sum of squared deviations 188.42 by n-1 which is 10. Range = 24, Standard deviation = 8.76, Variance = 76.67.
Detailed explanation-2: -Answer: The variance of the sample that has age of a 5 students 19, 20, 22, 16, 26 is, 13.8.
