This is a clarification for the quiz

the first Q is testing "cones you odered" vs "ice cream sold"

they are not talking about cusomers ordering these cones but the owner ordering these cones for  his shop.

the owner can order 100 cones  for the shop,but that doesn't mean he's gonna sell more or less, so there's no relationship

Q2  yes you can test this relationship for multiple reasons, one of them is the cost of the beer per state can affect the number of beer ordered
