Question
Based on the following values:
Mathematical expectation:
E(X) = ∑Xn1 = 1204 = 30
E(Y) = ∑Yn2 = 1884 = 47
E(Z) = ∑Zn3 = 1784 = 44.5
Variance:
var(X) = 1n1-1∑X2-1n∑X2 = 14-13678-12024 =26
var(Y) = 1n2-1∑Y2-1n∑Y2 = 14-18890-18824 =18
var(Z) = 1n3-1∑Z2-1n3∑Z2 = 14-18322-17824 =133.6667
Root mean square deviation
sd(X)= var(X) =26 = 5.0990
sd(Y)= var(Y) =18 = 4.2426
sd(Z)= var(Z) =133.6667 = 11.5614
