NO.PZ201709270100000303 3. Baseon Exhibit 1, whiinpennt variables in Varn’s mol are significant the 0.05 level? ESG only Tenure only Neither ESG nor tenure B is correct. The t-statistic for tenure is 2.308, whiis significant the 0.027 level. The t-statistic for ESG is 1.201, with a p-value of 0.238. This result is not significant the 0.05 level. 请问一下,(1)什么时候可以直接用给定的α和P值进行比较呢?(2)什么时候双尾也不用除以2?谢谢老师
请问若表格里有p值的话不是可以直接用p值和α直接比较吗?题目中的significanlevel 为0.05,双尾就是每边0.025,而题目中的p值都比这个大,因为得出not significance请问哪里有问题,谢谢
