Whether new university library would be useful for all students or not. Identify the sample.

Answer to Problem 5PPS
This is the biased sample.
Explanation of Solution
The sample as all students whose student ID number ends in 2 are surveyed is a biased sample the type of biased sample used in this data is the convenience sample.
As the new library is useful for all of the students but only survey the students whose ID’s ending with the number 2.
Conclusion:
Hence, this is the biased sample.
