Question

A condominium complex contains 20 units. The following data shows the number of individuals living in each unit. Using the first row of data as a sample, the sampling error is:

a) 0
b) 1
c) 2
d) 3

Answer 1

The sampling error given represents the maximum error bound, and one way to lower the sampling error is to increase the sample size.

Step-by-step explanation:

The sampling error given by the group of researchers who conducted the poll is ±3 percent. This represents the maximum error bound, meaning that the researchers estimate the percentage to be between 3 percent higher or lower than the reported value. To lower the sampling error, one way is to increase the sample size. This helps to reduce the variability within the data and provide a more accurate representation of the population.
