In an one-tail hypothesis test where you reject H0 only in the upper tail,what is the critical value

题目

In an one-tail hypothesis test where you reject H0 only in the upper tail,what is the critical value of the t-test statistic with 10 degrees of freedom at the 0.01 level of significance?

答案

意思是如果在做单侧T检验时在上尾区拒接零假设,那么按照拒绝标准为0.01,以及10个自由度的标准,你计算得到的t值应该是多少.
由于是单侧检验,所以0.01的标准查表时应该按照0.02的拒绝域来查双侧的t表,另外因为是上尾区,t应该为正的值,这样查表就能找到了~
