Answer:
a) 3.16
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given sample size 'n' =4</em>
mean of x⁻ = ∑x / n
= 
x⁻ = 16
Given data
x 13 14 17 20
x - x⁻ -3 -2 1 4
(x-x⁻)² 9 4 1 16
∑(x-x⁻)² = 9 + 4 + 1 +16 =30
The sample Variance
S² = ∑(x-x⁻)²/n-1

<em>The standard deviation of the sample </em>
<em> S = √10 = 3.1622 ≅3.16</em>
