To explain:
Difference between unbiased sample and a biased sample with example.

Answer to Problem 4E
Difference between unbiased sample and a biased sample is described as below.
Explanation of Solution
A biased sample when it is systematically favors some outcomes over other.
It is when the survey either encourages a particular response, does not provide enough information, are too sensitive to answer r addresses more than one problem.
For example, a police officer asks pedestrians “were you are the one who robbed the bank yesterday?”
This s biased sample as the pedestrians of course will say “no” regardless of the fact that they did rob it or did not.
An unbiased sample is when every individual or the element in population has an equal chance of being chosen.
For example, a police officer asks “should one build a park in this city”?
