The sample is not representative of the population.
Explanation of Solution
Given information:
The given information is:
Homes in the community-
Those surveyed
Calculation:
The objective is to determine whether the survey question is biased or not and then the sample is representative of the population.
In the sample it is chosen only
So, there may be chances to people whose age is less than 60 are also in the work during the day.
Also, the characteristics of sample and population are not same.
Thus, the sample chosen is biased.
Therefore,the sample is not representative of the population.
