A population consists of
N = 4
numbers: 16, 19, 24, 28 with a mean of
= 21.75.
A random sample of
n = 2
is selected.
How many possible random samples are there when sampling with replacement?
List the possible samples.
Find the sampling distribution for the sample mean x and display it as a table.
Display the sampling distribution for the sample mean x as a probability histogram.

We determined there are 10 possible samples of n = 2 from a population of N = 4 numbers: 16, 19, 24, 28. We found that {16, 16} and {16, 19} are two possible samples. List all 10 of the possible samples. (Enter your answers as a comma-separated list. Enter your answers in set notation. Enter each answer only once.)
