Re: I need helpp !! on this data!

A population consists of the following 5 values: 0, 2, 4, 5, 5.



Part (a) (1 point)

Calculate the population mean of these raw data.>>> Find the sum of the values and divide by the number of values there is --- that would be 5.



Part (b) (4 points)

List all possible samples of size 4 from the above population and compute the mean of each sample.
0, 2, 4, 5
0, 2, 5, 5
0, 4, 5, 5
2, 4, 5, 5
You finish. If you need more help, show us your work and some one will help.



Part (c) (1 point)

Calculate the mean of the sample means.



Part (d) (2 points)

Compare your answers from Parts (a) and (c) and comment on what you find.
