Pictured below (in scrambled order) are three histograms: One of them represents a population distribution. The other two are sampling distributions of x-bar; one for sample size n = 5, and one for sample size n = 30.

1. Which of the following 6 possible orderings of the three histograms represents the sequence:
   • Population distribution
   • Sampling distribution of x-bar for sample size n = 5
   • Sampling distribution of x-bar for sample size n = 30?
   • histogram 1, histogram 2, histogram 3
   • histogram 1, histogram 3, histogram 2
   • histogram 2, histogram 1, histogram 3
   • histogram 2, histogram 3, histogram 1
   • histogram 3, histogram 1, histogram 2
   • histogram 3, histogram 2, histogram 1
   
   
   
2. Based on the histograms, the most likely value of the population mean is:
   
   • 0.5
   • 3.0
   • 4.5
   • 7.5
   • 350
