问题如下:
If and its 95% confidence interval is [0.43,1.67], what is the t-statistic of ? What is the p-value of the t-statistic?
解释:
The standard error is(1.67 - 0.43)/(2 * 1.96)= 0.316.
The t-stat is then 3.31.
The two-sided p-value is 2(1- Φ(|t|))=0.09%
老师好,1、这里用的是什么分布?是z分布吗?
2、为什么纵轴对应的是红色框0和0.01?但是0.999517也没用上啊?
3、能画图解释一下吗?为什么0.999534是右尾?
