The relative frequency for middle school students whose favourite sport is baseball = 13/48 = 27%

The relative frequency for middle school students whose favorite sport is basketball = 15 / 48 = 31%

The relative frequency for middle school students whose favorite sport is football = 20 / 48 = 42%

The relative frequency for high school students whose favorite sport is baseball = 23 / 52 = 44%

The relative frequency for high school students whose favorite sport is basketball = 16 / 52 = 31%
