The sample space ...To find mean, we add up the values in a set and divide by the number of terms in that set. We begin this problem with the knowledge that the mean of the first set is 20. Since that set contains five numbers, we know that its total sum must be 100 (since 100 divided by 5 is 20). so must be 25. Now, the only step left is to find the mean of . B = {10;10;8;7;5} Solution: Hunter A. Hunter B. Variance of hunter A equals s 2 (A) = 0,4 , variance of hunter B equals s 2 (B) = 3,6. Stands s 2 (A) < s 2 (B). Hunter A won the competition.
