Answer: 0.74

Step-by-step explanation:

Standard Deviation, σ: 0.73702773119009

Count, N: 9

Sum, Σx: 53

Mean, μ: 5.8888888888889

Variance, σ2: 0.54320987654321

Steps:

σ2 =

Σ(xi - μ)2

N

=

(5 - 5.8888888888889)2 + ... + (7 - 5.8888888888889)2

9

=

4.8888888888889

9

= 0.54320987654321

σ = √0.54320987654321

= 0.73702773119009
