RES 351 Week 4 discussion 2

During the 2010 Super Bowl® game, the Snickers™ candy bar campaign was voted the best ad among men and women 18 and older and youth 18 or younger. The ad featured a neighborhood football game in which one of the players, who has dwindling energy, is tackled again and again. His teammates tell him, “You play like Betty White!” The 80-year-old actress and comedian appear in the ad as the football player being tackled. If you were the owner of the ADBOWL® website, how would you draw the sample to measure the best ad that aired during the Super Bowl® game among the three groups of interest?
