Consider the following population: (6, 7, 8, 9). For this population the mean is U=6+7+8+9 4 Suppose that a random sample of size 2 is to be selected without replacement from this population. There are 12 possible samples (provided that the order in which observations are selected 6,7 6,8 6,9 7,6 7,8 7,9 8,6 8,7 8,9 9,6 9,7 9,8 (a) Calculate the sample mean for each of the 12 possible samples. Sample Sample Mean 6,7 6,8 6,9 7,6 7,8 7,9 8,6 8,7 8,9 9,6 = 7.5 9,7 9,8 taken into account).
