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,请问为什么t-statistic对应的是P-value的范围呢? 能不能用区间的均值,比如(1.67-0.43)/2=0.62,对应的分布0.9115,然后1-0.9115=0.0885?
