WebJun 6, 2024 · S o, in order to find this p-value we need to use a T Score to P Value Calculator with the following inputs: The p-value for a test statistic t of 1.34 for a two-tailed test with 22 degrees of freedom is 0.19392. Since this number is greater than our alpha level of 0.05, we fail to reject the null hypothesis of our test.

WebDec 10, 2016 · To determine a p-value you need to specify whether it is one-sided or two-sided. For two-sided it is P ( X >15) and for one-sided lower tail it is P (X<-15) and P (X.>15) for one-sided upper tail. X is a chi-square random variable with 2 degrees of freedom. – Michael R.
