Answer #1

Solution :

=> standard deviation σ = 1.49

Explanation :

Given that 70 72 71 70 69 73 69 68 70 71

=> Mean x-bar = 70.3

=> sum of terms = 70 + 72 + 71 + 70 + 69 + 73 + 69 + 68 + 70 + 71 = 703

=> Number of terms = 10

=> Mean = sum of terms/Number of terms

= 703/10

= 70.3

=> standard deviation = 1.49 (rounded)
