Answer 1

Answer:

standard division is = 0.1830812661088

mark me as brainliest.

Explanation:

Standard Deviation, σ: 0.1830812661088

Count, N: 4

Sum, Σx: 101.13

Mean, μ: 25.2825

Variance, σ2:  0.03351875

Steps

σ2 =  

Σ(xi - μ)2

N

=  

(25.32 - 25.2825)2 + ... + (25.56 - 25.2825)2

4

=  

0.134075

4

=  0.03351875

σ =  √0.03351875

=  0.1830812661088
