When we are performing a 2 -tailed t statistic test, at level of significance ( alpha) =5 percent and p value = 2.7% :Do we compare p value with (alpha ) or with (alpha/2) ?? i .e. do we compare 2.7 percent with 2.5 percent ( 5/2) or 5 ?

hey amairalal, you should be comparing the p value with alpha, i.e. 2.7% vs 5% and reject null hypothesis
