Using the experimental sampling strategy, how many samples of size 4 (n = 4) can be drawn from the following population sizes? (a) N = 7 : samples (b) N = 8 : . samples (c) N = 9 : samples (d) N = 10 :
Homework Answers
The answer to all the parts can be given by NCn where n=4.
We are trying to select 4 data points from a population of N data points.
Therefore the possible number of selections must be equal to NCn = N!/((N-n)!*n!)
a) 7C4=35 samples
b) 8C4=70 samples
c) 9C4=126 samples
d)10C4=210 samples

Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 58 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible?

Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 60 bank accounts, we want to take a random sample of nine accounts in order to learn about the population. How many different random samples of nine accounts are possible?
