The first four moments of a distribution about the value 2 are 1, 2.5, 5.5 and 16. What is the 4th moment about zero?
168
The nth moment about zero is the sum of the nth powers of the deviations from zero. To calculate the 4th moment about zero, we use the formula and apply the given data. The answer is 168.
