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
1,2,4,8,12---------------------5.4
1,2,4,9,12---------------------5.6
1,2,5,8,9----------------------5
1,2,5,8,12---------------------5.6
1,2,5,9,12---------------------5.8
1,2,8,9,12---------------------6.4
1,4,5,8,9----------------------5.4
1,4,5,8,12---------------------6
1,4,5,9,12---------------------6.2
1,4,8,9,12---------------------6.8
1,5,8,9,12---------------------7
2,4,5,8,9----------------------5.6
2,4,5,8,12---------------------6.2
2,4,5,9,12---------------------6.4
2,5,8,9,12---------------------7.2
4,5,8,9,12---------------------7.6
2,4,8,9,12---------------------7

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 &#963;xbar = &#963; / &#8730;n
