有关于不良率推算及小概率验证问题,请指教

已经累积一组检测数据,已知 公差范围
可以推算出接下来,生产中的不良率大概是多少吗?
附件带有数据。如果可以可以做个范例吗?先谢谢了
另外考虑到,我们客户每次发现一个不良,就会投诉,能不能通过检测后续生产中的数据,然后进行推算,推算其发生不良是否是一个小概率事件?
具体数据,137~143上下限

赞同来自:

1,关于正态:并不是抽样数据越多,越正态,
2,你这个数据取前150个时,p=0.052,差不多正态,。再多数据需要提高精度才能正态,不然重复性数据太多
3,
取150数据_的_Process_Capability_Sixpack_报告.jpg
