@CrazyCountryGirl  its a straight forward question...it simply says that u hav collectd information on income of different and last four digits of their phone number...it doesnt state the the relationshiip between the income and last four digits...and that is just screwing my mind...and it isnt mentioned anywhere that their income r same...nevertheless i guess u r correct

Can there be any relationship between `income` and `the last four digits of their phone numbers` ?

ganeshie8 · Answer

No, there can not be any relationship - so you should see a fully scattered scatter plot
