Mean weight of 8 students is 46.5kg
Therefore total weight = 8 × 46.5 = 372
Add three students weighing = 372+41.7+52.8+51.8 = 518.3
Therefore, Mean = 518.3/11 students
= 47.11 Kg
Therefore total weight = 8 × 46.5 = 372
Add three students weighing = 372+41.7+52.8+51.8 = 518.3
Therefore, Mean = 518.3/11 students
= 47.11 Kg
