The population (actual) has least variance, & as we take larger & larger the sample the variance of sample becomes consistent (nearly equal) to the actual population variance.
based on the given histogram's, last histogram has least variance so this histogram indicates the population distribution.
then, the first histogram shows nearly same picture as population with larger variance ,so this could indicate the sample with size= 30. And second histogram Indicates sample with size= 5 since it has largest variance.
### Answer:
population distribution ----> last histogram (3)
sampling distribution with n= 5. ----> second histogram (2)
sampling distribution with n= 30. ----> first histogram (1)
