The correct ordering is :
- histogram 2 , histogram 3 , histogram 1
since , sampling distribution of the sample mean will tend to follow more Normal if we increase the sample size, if its population distribution is skewed . That is why the more bell shaped histogram ( histogram 1) is representing sampling distribution of x-bar for sample size n =30 , slighty less bell shaped histogram ( histogram 3) is representing sampling distribution of x-bar for sample size n =5 , and the positively skewed histogram ( histogram 2) is representing the populatin distribution .
