IR 黄金50题的16A,
B is a boy aged 4 years 3 months whose height is 110 cm and whose weight is 19 kg. For each of the following statements, selectYes if, based on the given information, it must be true of B relative to a model population. Otherwise, select No. 怎么觉得这个题应该选No啊, 答案的解释是取110cm时15%的weight 大概是17 kg,而19kg>17Kg, 所以说at least 15% of boy...
而我看图上,110cm对应50%时的体重明显是<19Kg的,应该是 at least 50% of boy,所以我就选的 No.
是不是 15%比较宽松 ,所以题目说的是正确的??不理解 ,求解答
| | Yes | No | | | 16A. | | | At least 15% of boys at the same height have a weight that is less than or equal to that of B. |
