甲乙两个学校高三年级分别为1100人，1000人，为了统计两个学校在地区二模考试的数学科目成绩，采用分层抽样抽取了105名学生的成绩，并作出了部分频率分布表如下：（规定考试成绩在[120，150]内为优秀）
甲校：
分组[70，80）[80，90）[90，100）[100，110）[110，120）[120，130）[130，140）[140，150）
频数23101515x31
乙校：
分组[70，80）[80，90）[90，100）[100，110）[110，120）[120，130）[130，140）[140，150）
频数12981010y3
（1）计算x，y的值，并分别估计两上学校数学成绩的优秀率；
（2）由以上统计数据填写下面2×2列联表，并判断是否有97.5%的把握认为两个学校的数学成绩有差异．
 甲校乙校总计
优秀   
非优秀   
总计   
附：k2=
n(ad-bc)2
(a+b)(c+d)(a+c)(b+d)

P（k2≥k0）0.100.0250.010
k02.7065.0246.635
答案

（1）依题甲校抽取55人，乙校抽取50，

故x=6，y=7

估计甲校优秀率为

10
55
=18.2%

乙校优秀率为

20
50
=40%

（2）根据所给的条件列出列联表

 甲校乙校总计
优秀102030
非优秀453075
总计5550105
k2=
105×(10×30-20×45)2
55×50×30×75
=6.109

又因为6.10＞5.024

故有97.5%的把握认为两个学校的数学成绩有差异．
