5. Consider this group of numbers to be a population: 5 , 15 , 20. Put the three numbers into L . From this population, list all the possible samples of size 2. List the mean of each sample and find the mean of the sample means. Compare this to the population mean. Show all of your work. X X u from L, = 4 2 5 6 = Find the standard deviation of the population. Put the means into L2 , and find the standard deviations for this list. Then divide o by v2 , and compare it to o- . o from L = 2 s- from Lz = o- from L2 =
