I have a problem in which i have no idea how to solve b through D

Math 251

1. A population consists of these values: 2, 3, 6, 8, 11, 18. We do a sampling

without replacement.

(a)

Find

the mean and the population standard deviation.

(b)

List all samples of size N = 2

that can be obtained without replacement. (c)

(c)

Find the population of all values of

x bar

by finding the mean of each sample from part (b). (d)

(d)

Find the mean

and standard deviation

for the population of sample means found in part (c). (e)

Verify that xbar = mue and s= sigma/thesquare root of N|N-n

N-1 square root.

Please help i figured out part A the mean and population standard deviation but i'm so confused for B
