Suppose a population consists of the five measurements: 2, 6, 8, 0, and 1:
1. What is the mean and standard deviation of the population?
2. How many different samples of size n=2 can be drawn from the population? List them with their corresponding means.
Follow the step by step procedure.
2. Number of samples
m(2,6)=(2+6)/2=4
m(2,8)=(2+8)/2=5
m(2,0)=(2+0)/2=1
m(2,1)=(2+1)/2=1.5
m(6,8)=(6+8)/2=7
m(6,0)=(6+0)/2=3
m(6,1)=(6+1)/2=3.5
m(8,0)=(8+0)/2=4
m(8,1)=(8+1)/2=4.5
m(0,1)=(0+1)/2=0.5
