EXAMPLE 1.48

StubHub! StubHub! is a website where fans can buy and sell tickets to sporting events. Ticket holders wanting to sell their tickets provide the location of their seats and the selling price. People wanting to buy tickets can choose from among the tickets offered for a given event.³⁴

Tickets for the 2015 NCAA women’s basketball tournament were available from StubHub! in a package deal that included the semifinal games and the championship game. On June 28, 2014, StubHub! listed 518 tickets for sale. A histogram of the distribution of ticket prices with a density estimate is given in Figure 1.32. The distribution has three peaks: one around $700, another around $2800, and the third around $4650. This is the identifying characteristic of a trimodal distribution. There appears to be three types of tickets. How would you name the three types?
