Q1) Voting behaviour is examined for random sample of population, by researchers who are interested in relationship between voting behaviour and many different demographic variables. Members of the sample are asked the following:
i) Their gender (male or female),
ii) Their income bracket (in quartiles)
iii) Their ethnic origin (recorded as Latin American, European, African, East Asian, Middle Eastern, South Asian, or Aboriginal American).
If these answers were combined into single statistic, how could we explain sample space? Mention how many elements are in sample space?
