A researcher is interested in determining purchasing preferences based
on age. The researcher randomly samples people in two age groups and
asks how they prefer to shop. Conditional percentages are used to
summarize the responses in the table below:

39 and below..63%.....37%.......100%
Total.........54%.....46%.......100%
Based on this information, what is the relationship between age and
shopping preference?
A) People aged 40 and above prefer shopping in-store more than
people aged 39 and below because 55% is greater than 45%.
,B) People aged 40 and above prefer shopping in-store more than
people aged 39 and below because 55% is greater than 37%.
C) People aged 39 and below prefer shopping in-store more than
people aged 40 and above because 63% is greater than 46%.
D) People aged 39 and below prefer shopping in-st - ✔✔✔ Correct
Answer > People aged 40 and above prefer shopping in-store more than
people aged 39 and below because 55% is greater than 37%.
