Determine if a real life situation is a function or not
I will give 2 instances
(1) Students and their ID
The relationship is as follows:
Student 1 -----> ID-1
Student 2 -----> ID-2
Student 3 -----> ID-3
Student 4 -----> ID-4
---------
----
--
Student n -----> ID-n
The above is a function because every student has a unique student ID.
In fact, the relation is a one-on-one function because no two students will have the same ID
(2) People and their year of birth
The relationship is as follows:
Person 1 -----> 2000
Person 2 -----> 2001
Person 3 -----> 2002
Person 4 -----> 2001
---------
----
Person n -----> 2005
The above is not a function because there is a possibility that a more than one person will have the same year of birth.

C) No, this method would not generate an SRS of local voters because not everybody will be pick up when they call because they may not be at home or they may be too busy to pick up.
D) No, this method is not unbiased in generating samples of households because there will be nonresponse bias since not everyone will pick up the call
