Follow-up Question

I need the second part of the attached question answered.I have attached the solution for the first part as well as the question.

Step 1
As per our guidelines we have to answer the first question if multiple questions are posted at a time.
Please repost the rest to be answered.
Step 2
We know that,
σ=
√x:
Σ (x – μ)
N
Standard deviation =
Where µ- mean of the observations.
Given: N= 10
Mean(u) = 1+2+3+...+10/10=55/10 = 5.5
Step 3
Σ(x-μ)2 = (1-5.5)2 + (2-5.5)2 +...+ (10-5.5)²
= 82.5
Σ(x-μ)2/N = 82.5/10 = 8.25
Standard deviation = √8.252.872281323.
