Question

Two recreational tennis teams, Westside and Eastside, wanted to compare the ages of their players. The ages of the Westside players are 20, 21, 21, 22, 23, 24, and 24. The mean age of the Westside players is 22 The ages of the Eastside players are 22, 23, 23, 24, 24, 26, and 26. The mean age of the East side players is 24 Which statement is true? The range of Team Westside's players ages is greater than the range of Team Eastside's players ages. Team Eastside's players ages vary more than Team Westside's players ages. Team Westsides's players ages vary more than Team Eastsides's players ages. Team Eastside's players ages vary the same amount as Team Westside's players ages

Answer 1

We have two sets of values: the ages of Westside players and the ages of Eastside players.

Ages of the Westside players = [20, 21, 21, 22, 23, 24, 24]

Ages of the Eastside players = [22, 23, 23, 24, 24, 26, 26]

We can evaluate the mean of each set as:
