Identify following case whether biased or unbiased: Determining weekly top 10 songs by voting on respective web site.

Answer to Problem 27SGR
Determining weekly top 10 songs by voting on respective web site is an example of voluntary response biased sample.
Explanation of Solution
Given:
Determining weekly top 10 songs by voting on respective web site.
Calculations:
Here, we have to justify whether given example is biased or unbiased.
Biased samples are the samples that are most likely to be considered than others in whole population.
Unbiased samples are the samples in which almost all members are included in the population
Given example is voluntary response type biased sample as only interested people will participate in voting of their favorite song.
In voluntary response type biased sample, members voluntarily participate in survey.
Conclusion:
Therefore, we are able to define whether given sample is biased or unbiased.
