Find the mean, variance and standard deviation of the following measures 2,5,6,3,9,10,12
We have population values 2,5,6,3,9,10,12, population size N=7.
Mean of population "(\\mu)" = "\\dfrac{2+5+6+3+9+10+12}{7}=\\dfrac{47}{7}"
Variance of population
"+\\dfrac{676}{49}+\\dfrac{256}{49}+\\dfrac{529}{49}+\\dfrac{1369}{49})=\\dfrac{584}{49}\\approx11.918367"
