The marketing manager of a manufacturer of sports cards plans to begin a series of cards with pictures and playing statistics of former major league baseball players. At the baseball card show at a mall last weekend, she set up a booth and offered cards of the following six Hall of Fame baseball players: Dizzy Dean, Bob Feller, Phil Rizzuto, Warren Spahn, Mickey Mantle, and Willie Mays. At the end of the first day, she sold a total of 120 cards.

1. Dizzy Dean 13
2. Bob Feller 33
3. Phil Rizzuto 14

Can she conclude that the sales of cards are the same for the six players? Use a 5% level of significance?
