1 . 某疾病预防中心随机调查了340名50岁以上的公民,研究吸烟习惯与慢性气管炎患病的关系,调查数据如表所示.
(1)是否有95%的把握认为患慢性气管炎与吸烟有关?
(2)常用
表示在事件A发生的条件下事件B发生的优势,在统计中称为似然比.现从340人中任选一人,A表示“选到的人是吸烟者”,B表示“选到的人患慢性气管炎者”请利用样本数据,估计
的值;
(3)现从不患慢性气管炎者的样本中,按分层抽样的方法选出7人,从这7人里再随机选取3人,求这3人中,不吸烟者的人数X的数学期望.
不吸烟者 | 吸烟者 | 总计 | |
不患慢性气管炎者 | 120 | 160 | 280 |
患慢性气管炎者 | 15 | 45 | 60 |
总 计 | 135 | 205 | 340 |

(2)从2023年元旦及前后共7天中任取3天,将这3天中交通高峰期城市道路TPI比2022年同日TPI高的天数记为X,求所有X的可能值及其发生的概率.
