Because most National Football League games are sold out, the secondary market, in which people resell their tickets, is very active during the season. The following table shows the price for secondary market tickets to the games of four NFL teams. These data can also be found in the Excel file NFL tickets.xlsx.

Green Bay Packers ($)

New Orleans Saints ($)

Indianapolis Colts ($)

New York Jets ($)

213 197 170 197 190 198 152 151 185 216 165 184 188 199 166 188 214 220 165 182

a. Perform a one-way ANOVA using a = 0.05 to determine if there is a difference in the average ticket prices for the four NFL teams.

b. If warranted, perform a multiple comparison test to determine which pairs are different using a = 0.05.
