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

I think this is great, thank you. 

Could you please check the additional hypothesis in the image below

8) Verification of a hypothesis of equality of the mathematical expectation of two random quantities HO: mx=my; H1: mx #my 9) Verification of a hypothesis of equality of the mathematical expectation of two random quantities H0: my= mz; H1: my#mz 10) Verification of a hypothesis of equality of the mathematical expectation of two random quantities HO: mx = mz; H1: mx #mz 11) Testing a hypothesis whether x* is a gross error. Check the maximum and minimum values, if they are gross errors 12) Check if y* is a gross error. Check the maximum and minimum values if they are gross errors.
