The population of the size of the households of my immediate family members has a Mean =3.6, median=4, range= 5, standard deviation=1.85472, variance=3.439.
Now consider the possible random samples from this population with n=2(you should identify 25 such samples). For each of these samples, compute the mean, median, range, standard deviation and variance (hint: with n=2, the median is the same as the mean).
At this point, you should have produced five data sets (four distinct) with 25 data value each: find the mean (only the mean) of each of these sets.
