Part J:
The two categories of interest are the “average money” of a person and the “number of problems he or she may have”.
The hypotheses to be tested are:
Null hypothesis:
H0: The average money of a person and their problems are independent.
Alternative hypothesis:
Hα: The average money of a person and their problems are not independent.
Evidently, the test is to determine whether a person’s money can help to determine their problems.
Thus, the study seeks to find whether there is any association between the two categories “average money” of a person and the “number of problems he or she may have”. In other words, the study aims to test whether these two categories are independent or not.
As the necessary assumptions are considered to be satisfied, the appropriate test to be performed is (i) Chi-square test for independence.
Answer:
J. The most suitable test is (i) Chi-square test for independence.
