Question 360203
Here are the numbers of sales per day that were made by a telemarketer who worked four days before being fired: 1, 11, 9, 3. Assume that samples of size 2 are randomly selected with replacement from this population of four values. 
a. List all the possible samples and find the mean of each. 
1/11:::mean = 6
1/9::::mean = 5
1/3::::mean = 2
---
11/9:::mean = 10
11/3:::mean = 7
---
9/3::::mean = 6
=============================
b. Identify the probability of each sample, 
then create the sampling distribution of sample means.
---
Not sure what you want here. 
----------
c. Find the mean of the sampling distribution. 
sum of the means = 36
# of sample means = 6
---
Mean of the sample means: 36/6 = 6
