一道难的统计题目,谢谢大家回答
A company is considering the use of self-managed work teams. A random sample of 400 employees is selected and their attitudes toward self-managed work teams are recorded. The results classified by their type of job are shown in the following table.
Attitude toward self-managed work teams:
Hourly worker: (Favour)108 (Neutral)46 (Against)71
Supervisor: (Favour)18 (Neutral)12 (Against)30
Middle management: (Favour)35 (Neutral)14 (Against)26
Upper management: (Favour)24 (Neutral)7 (Against)9
Are the type of job and attitude toward self-managed work teams independent at 1% level of significance?

一家公司正在考察自我管理工作小组的效果.随机抽取了一个400员工的样本,并且记录下他们对自我管理工作小组的态度.把他们按照工作类型分类,结果列于下表.
对自我管理工作小组的态度：
钟点工：（支持）108（普通）46（反对）71
主管：（支持）18 （普通）12（反对）30
中层管理人员：（支持）35 （普通）14（反对）26
高层管理人员：（支持）24 （普通）7 （反对）9
以1%作为衡量的参数考虑员工的岗位分类和他们对自我管理工作小组的态度是否独立?
