Question

A student measuring how gasoline prices change records the cost of gas at 10 randomly selected stations in her hometown. One week​ later, she records the price again at the same 10 stations. Are these data paired or​ independent?

Answer 1

Independent- meaning that the probabilities are not changing
Dependent- meaning that the probabilities are changing
I would guess paired because the prices are changing, meaning that the probabilities are also changing.
