3.898717738 is the standard deviation.
49.30179172 is the standard deviation and 52 is the mean.
2√(17/21), or about 1.8.
The distribution of x can be almost anything - apart from the Poisson distribution.
21 over 11 = 21/11 in fraction

√2.5
2√(17/21), or about 1.8.
The distribution of x can be almost anything - apart from the Poisson distribution.
The formula for the standard deviation of a sample (s) is given by: s =√(⅟₍n₌₁₎Σ(y-ȳ)²) where y are the data points and ȳ is their mean; it can be rearranged to give: s = √(⅟₍n₌₁₎(Σy² - n((Σy)/n)²) → s = √(⅟₍₅₌₁₎(1815 - 5(⁹⁵/₅)²) → s = √(¼ × 10) → s = √2.5
