2) A local apartment complex has 25 units. The number of individuals living in each unit is presented in the table below.
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
Using the first and fith rows as a sample, the sampling error is...

Population mean =73/25 =2.92

Sample mean =32/10=3.2

The sampling error is the difference between a sample statistic used to estimate a population parameter

sampling error = sample mean – population mean =3.2-2.92=0.28

we overestimate mean by 0.28.
