Para encontrar a moda, precisamos identificar o valor que mais se repete no conjunto de dados. No caso, temos os seguintes valores de idade: 14, 14, 16, 30, 32, 33, 35, 36, 37, 39, 39, 40, 41. O valor que mais se repete é 39, portanto, a moda é 39. Para encontrar a média, somamos todos os valores e dividimos pelo número total de valores. Somando todas as idades, temos: 14 + 14 + 16 + 30 + 32 + 33 + 35 + 36 + 37 + 39 + 39 + 40 + 41 = 426. Dividindo esse valor pelo número total de idades (13), obtemos a média de aproximadamente 32,77. Portanto, a resposta correta é a alternativa: a) 16, 25 e 19
