A Pullman local sports store is interested in consumerpurchasing likelihood of WSU gear (1=not at all to 7=very much)before and after a win in football.

A marketing researcher has heard that when kids areanonymous, they'll take more candy. To test this hypothesis, shebrings 6 kids into a specially-constructed Halloween Lab with tworooms. Each room is identically decorated and contains a decoratedfront porch, a front door, and a doorbell. Behind the door is aconfederate who will answer the door and offer a bowl of candy. Thetwo rooms differ only in their lighting conditions. One room islight; one room is dark, the latter presumably leading to greateranonymity. She says, ok kids, I want you to go into each roomand interact with the person behind the door as you would normallyinteract during Halloween. Ring the doorbell, say trick or treat,and then take some candy. So, the kids do this and theresearcher measures how many pieces of candy they take. The dataare shown below. Do kids take more candy under conditions that makethem feel anonymous? Use alpha = .10.
