Answer:

The sample mean is $58 and population mean is $68.

Step-by-step explanation:

Since, They do a survey on only 1500 households and use only this information to get mean. So, Sample Mean is $58 whereas Population Mean is $68.

When we get information using all possible units, Then it is Population.

The sample is a subset of the population. We take samples because it is easy to analyze samples as compared to population and it is less time taken.
