ada a tabela: Qual o ponto médio na tabela de classes? Escolha uma opção: a. 2,5; 7,5; 12,5; 17,0; 22,0; 27,5. b. 2,0; 7,0; 12,0; 17,0; 22,0; 27...

Para encontrar o ponto médio de cada classe, basta somar o limite inferior e o limite superior de cada classe e dividir por 2. Assim, temos: - Classe 1: 1,0 - 4,0 -> (1,0 + 4,0) / 2 = 2,5 - Classe 2: 4,0 - 7,0 -> (4,0 + 7,0) / 2 = 5,5 - Classe 3: 7,0 - 10,0 -> (7,0 + 10,0) / 2 = 8,5 - Classe 4: 10,0 - 13,0 -> (10,0 + 13,0) / 2 = 11,5 - Classe 5: 13,0 - 16,0 -> (13,0 + 16,0) / 2 = 14,5 - Classe 6: 16,0 - 19,0 -> (16,0 + 19,0) / 2 = 17,5 - Classe 7: 19,0 - 22,0 -> (19,0 + 22,0) / 2 = 20,5 - Classe 8: 22,0 - 25,0 -> (22,0 + 25,0) / 2 = 23,5 Portanto, a alternativa correta é a letra A) 2,5; 7,5; 12,5; 17,0; 22,0; 27,5.
