Question

the first four moments of data about 2 are 1, 2.5, 5.5 and 16.Find the first four moments about mean and zero

Answer 1

Step-by-step explanation:

Given the first four moments of data about 2 are 1, 2.5, 5.5 and 16. Find the first four moments about mean and zero

• Now x1 = 1, x2 = 2.5, x3 = 5.5, x4 = 16
• So the first moment about mean is equal to sum of observation / total number of observation
•                                                                    =  x1 + x2 + x3 +………….xn) / n
•    So we have                                                          = 1 + 2.5 + 5.5 + 16 / 4
•                                                                                   = 25 / 4
•                                                                                   = 6.25
• Therefore the moment about mean will be 6.25
