10 . 某市联考后从全体考生中随机抽取42名,获取他们本次考试的数学成绩
和物理成绩
,绘制成如图散点图:
与
之间有线性相关关系,但图中有两个异常点
.经调查得知,
考生由于重感冒导致物理考试发挥失常,
考生因故未能参加物理考试.为了使分析结果更科学准确,剔除这两组数据后,对剩下的数据作处理,得到一些统计的值:
,其中
,
分别表示这40名同学的数学成绩、物理成绩,
与
的相关系数
.
(1)若不剔除
两名考生的数据,用42组数据作回归分析,设此时
与
的相关系数为
.试判断
与
的大小关系,并说明理由;
(2)求
关于
的线性回归方程,并估计如果
考生参加了这次物理考试(已知
考生的数学成绩为126分),物理成绩是多少?
(3)从概率统计规律看,本次考试该市的物理成绩
服从正态分布
,以剔除后的物理成绩作为样本,用样本平均数
作为
的估计值,用样本方差
作为
的估计值.试求该市共40000名考生中,物理成绩位于区间
的人数
的数学期望.
