A number of studies have examined how alcohol consumption affects neuroticism using an animal model.  Two kittens are randomly selected from each of 7 litters (two cats from each litter).  One cat from each pair is assigned to the experimental group which is subjected to a procedure that induces temporary neurosis. The other cat from each pair is part of the control group (no neurosis induction). All the cats are then offered milk spiked with 5% alcohol.  The amount of milk consumed in three minutes is measured (in milliliters). Do the kittens in the experimental group drink more alcohol than the kittens in the control group?   What test should you use and why?
