Answer:

3.4 nearest tenth

Step-by-step explanation:

Standard Deviation, σ: 3.4399612400917

Count, N: 12

Sum, Σx: 144

Mean, μ: 12

Variance, σ2:  11.833333333333

Steps

σ2 =  Σ(xi - μ)2

N

=  

(14 - 12)2 + ... + (10 - 12)2

12

=  

142

12

=  11.833333333333

σ =  √11.833333333333

=  3.4399612400917

Hope this helps ya!

Sorry this didn't have the symbols I needed so that's why it's a little confusing.
