(a) Suppose a sample of size 2 is randomly selected from the population, with replacement, as follows. One customer is randomly selected, their rating is recorded, and the customer is put back into the \"pool\" to be chosen from. Then for a second time a customer is randomly selected and their rating is recorded. There are 9 possible samples. The ratings for several of the possible samples have been listed in the table below. Enter the ratings for the remaining possible samples. When you are done, select \"Compute\". In the \"Sample mean, $\bar{x}$ \" column, you will then see the sample mean of the ratings for each sample, along with the mean and standard deviation of all the column's values.
