Can waitresses increase their tips simply by introducing themselves by name when they greet customers? A waitress collected data on two- person parties that she waited on during Sunday brunch (with a fixed price of $$price) at a Charley Brown's restaurant in southern California. For each party the waitress used a random mechanism to determine whether to give her name as part of her greeting or not. Then she kept track of how much the party gave for a tip at the end of their meal. The sample mean tip amount for the 20 parties to which the waitress gave her name was $5.44, with a standard deviation of $1.75. These statistics were $3.49 and $1.13, respectively, for the 20 parties to which the waitress did not give her name. The data were not strongly skewed in either group. Use appropriate symbols for the six numbers reported in this paragraph. nName = i X Name = $ SName = $ i nNoName = i XNoName = $ i SNoName = $ i
