The relative frequency table below summarizes a survey about support for candidate X in an upcoming national
election. In this survey, 210 randomly selected Virginians opposed candidate X.
How many people in this survey were Californians who opposed candidate X?
Does the table show evidence of an association between being from Virginia and opposing candidate X?
Choose all answers that apply:
Yes, because Virginians who oppose candidate X have the smallest joint relative frequency.
B
Yes, because 58.3% of people who oppose candidate X are from Virginia, but only 50% of all
people in the study are from Virginia.
Yes, because 70% of Virginians oppose candidate X but only 58.3% of people who oppose
candidate X are Virginians.
D
Yes, because 70% of Virginians oppose candidate X, but only 60% of all people oppose him.
No, because the total column percentages are equal.
