The frequency polygon below represents the weights of players who all participated in the same sport. Use the polygon to answer the following questions: (2 marks each, with an explanation for each answer) [10] Weights of Sport Players 20- 18- Number of Students 12- 55 65 75 85 95 105 Weights of Students (kg)a} How many players played the sport? b} What was the most common weight for the players? e] What sport do you think the players may have been playing? d) What do the weights of 55 kg and 1135 kg represent? e} What 2 weights haye no recorded players weighing these amounts? 3.
