Get step by step solution for Kurtosis, Variance, Mean, and Super Skewness?

Hello,

Please, why Mathematica is not shown the step for the solution for Kurtosis,Variance, and Mean for the Normal Distribution? I used below code but its gave the result only.In addition, Can Mathematica find SuperSkewness (for example 6) and mean of fluctuation to any symbol like (2n-1), (2n+1)? Kurtosis

WolframAlpha["Kurtosis[NormalDistribution[\[Mu],\[Sigma]]]"]

Variance

WolframAlpha[" Variance[NormalDistribution[0,\[Sigma]]]"]

Mean

 WolframAlpha[" Mean[NormalDistribution[\[Mu], \[Sigma]]]"]

Hello,

Thank you for your reply. I am doing that to get steps for the solution.This way it only gave me the answer.

I don't know why you would use WolframAlpha to do this; you can get this directly in Mathematica:

CentralMoment[NormalDistribution[\[Mu], \[Sigma]], #] & /@ Range[6]

gives the first 6 central moments:

{0, \[Sigma]^2, 0, 3 \[Sigma]^4, 0, 15 \[Sigma]^6}
