Question options:

A. 1.63

B. 0.47

C. 0.94

D. 1.15

Answer:

A. 1.63

Step-by-step explanation:

To find the standard deviation,

we have the data:

6, 6, 10, 8, 10, 8

sum = 6 + 6 + 10 + 8 + 10 +8

= 48

mean = 48 / 6

= 8

Formula for standard deviation:

σ2 = Σ(xi - μ)2 / N

= Σ (6-8)2 +....+ (8-8)2 / 6

= 16 / 6

σ2= 2.67

σ =
`√(2.67)`

σ = 1.63
