A local apartment complex has 25 units. The number of individuals living in each unit is presented in the table below.
Using the second and fifth columns as a sample, the sampling error is:
| 2 | 3 | 4 | 5 | 1 | 
| 2 | 5 | 2 | 2 | 4 | 
| 3 | 2 | 3 | 4 | 3 | 
| 1 | 1 | 1 | 3 | 5 | 
| 4 | 3 | 3 | 5 | 2 | 
Solution
true mean = 2.92...sample mean = 2.9.........
 sampling error = 2.9 - 2.92 = - 0.02.....
