The question below appears in the attached file as well. You may find it easier to read in the attachment.

Given the following population data: 1,2,4,5,8,9,12, and the lists of all samples of size 2 and 5:

Samples of n=2 -xbar

1,2--1.5

1,4--2.5

1,5--3

1,8----------------------4.5

1,9----------------------5

1,12---------------------6.5

2,4----------------------3

2,5----------------------3.5

2,8----------------------5

2.9----------------------5.5

2,12---------------------7

4,5----------------------4.5

4,8----------------------6

4.9----------------------6.5

4,12---------------------8

5,8----------------------6.5

5,9----------------------7

5,12---------------------8.5

8,9----------------------8.5

8.12---------------------10

9.12---------------------10.5

For population

s = ?

m = ?

For n = 2

sxbar = ?

mxbar = ?

For n = 5

sxbar = ?

mxbar = ?

Samples of n=5----------------xbar

1,2,4,5,8----------------------4

1,2,4,5,9----------------------4.2

1,2,4,5,12---------------------4.6

1,2,4,8,9----------------------4.8

a) Use Excel to find the six ? values above.

b) Consider the three values of mean and the three values of standard deviation in a). Verify (mathematically) that the Central Limit Theorem applies using the formulas:

µ = µxbar and σxbar = σ / √n

c) Why are your answers from a) and b) slightly off?
