老师您好,当Z值或者T值<K值时,我们说接受H0的假设,但是这里我想问一下Z值或者T值<K值的意义是什么?以本课中举的例子为例,T值=(1.5%-1.1%)/(3.6%/√20)=0.497<K=2.093,那么这个结论代表了什么意思呢?X拔=1.5%落在正态分布(1.1%, δ)中的概率???烦请老师以图片中的例题为例解释下T值<K值代表的意义,十分感谢
As a result of manipulating interest rates the economy exhibits fluctuations that would not have happened otherwise。请问这句话什么意思?
