The Census Bureau website gives several choices for "average income" in its historical income data. In 2017, the median income of American households was $68,145. The mean household income was $93,453. The median income of families was $75,938, and the mean family income was $100,400. The Census Bureau says, "Households consist of all people who occupy a housing unit. The term 'family' refers to a group of two or more people related by birth, marriage, or adoption who reside together." Explain carefully why mean incomes are higher than median incomes and why family incomes are higher than household incomes.
On December 17, 2007 baseball writer John Hickey wrote an article for the Seattle P-I about increases to ticket prices for Seattle Mariners
games during the 2008 season. The article included a data set that listed the average ticket price for each MLB team, the league in which the team
plays (AL or NL), the number of wins during the 2007 season and the cost per win (in dollars). The data for the 16 National League teams are shown
below.
