Quizplus · Accepted Answer

The p-value for a two-tailed test can be found using the test statistic and looking up the corresponding value in a standard normal distribution table or using statistical software. A test statistic of 2.5 corresponds to a p-value of approximately 0.0124 for a two-tailed test, indicating the probability of observing a test statistic as extreme as 2.5 or more extreme, assuming the null hypothesis is true.
