1. ). A resort area has three seafood restaurants, which employ students during the summer season. The local chamber of commerce took a random sample of five servers from each restaurant and recorded the tips they received on a recent Friday night. The results (in dollars) are shown in the table below. Assume the Friday night for which the data were collected is typical of all Friday nights of the summer season.

Restaurant	Amount in Tips Received
Barzini's	97, 114, 105, 85, 120
Hwang's	67, 85, 92, 78, 90
Jack's	93, 102, 98, 80, 91
