Sheena obtains cash from an ATM machine. She suspects that the rate at which she spends the cash is affected by the amount of cash she withdrew at her previous visit to an ATM. To investigate this she deliberately varies the amount she withdraws. She records for her each visit to an ATM, the amount "x"(in $) withdrawn and the number of hours "y" until her next visit to an ATM.
