how to get p value from hypothese test

testing One-Sided Hypothesis Test with T-Statistic in R

p-value = the probability of obtaining a test statistic at least as extreme as the one from the data at hand, assuming the model assumptions are all true, and the null hypothesis is true, and the random variable is the same (including the same population), and the sample size is the same.

Frequentist Hypothesis Tests p-values and Type I Error

Because we rejected the null hypothesis, we now approximate the p-value which is the likelihood of observing the sample data if the null hypothesis is true. An alternative definition of the p-value is the smallest level of significance where we can still reject H 0 .

Five P Value Tips to Avoid Being Fooled by False Positives

If the test statistic is more extreme in the direction of the alternative than the critical value, reject the null hypothesis in favor of the alternative hypothesis. If the test statistic is less extreme than the critical value, do not reject the null hypothesis.

Five P Value Tips to Avoid Being Fooled by False Positives

Sir Ronald A. Fisher. When a statistical hypothesis test produces significant results, there is always that chance that it is a false positive. In this context, a false positive occurs when you obtain a statistically significant P value, and you unknowingly reject a null hypothesis that is actually true.
