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.
b. Identify the probability of each sample, then create the sampling distribution of sample means.
c. Find the mean of the sampling distribution.

You can put this solution on YOUR website! 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
=================
