Hey guys this may be a dumb question, but it is pertaining to the following question from GMAT prep.
Are at least 10% of people 65 and older employed?
A) 11.3% of the population is 65 or older
B) Of those 65 and older, 20% of the men and 10% of the women are employed.
[spoiler]OA: B[/spoiler]
I chose B, but I was wondering because the question is asking if AT LEAST 10% of the people 65+ are employed...
..could we have generalized that as long as the splits (men/women employed) are each greater than 10% then the aggregate sample will be greater than 10%? In other words is there a 'percentage threshold' about making generalizations about a population, from a split up sample?
