Given below are moments about an arbitrary origin 5.
If μ'1 = -4, μ'2 = 22, μ'3 = -117 and μ'4 = 560, then μ3 is equal to:
19
To convert central moments from moments about arbitrary origin, use the transformation formulas. For the third moment: μ3 = μ'3 - 3μ'1μ'2 + 2(μ'1)3
= -117 - 3(-4)(22) + 2(-4)3 = -117 + 264 - 128 = 19.
