Web7 TEST STATISTIC = a tool for testing the hypothesis • its value depends on the sample • two components: • value of test-function • critical value(s) rejecting region • significance level (α): the probability that the test-function falls into the rejection region • testing one or two population parameters. 8 1 POPULATION WebNov 13, 2024 · One of the most commonly used p-value is 0.05. If the calculated p-value turns out to be less than 0.05, the null hypothesis is considered to be false, or nullified (hence the name null hypothesis). And if the value is greater than 0.05, the null hypothesis is considered to be true. Let me elaborate a bit on that.

In our example, if we obtain a sample mean of 550, the p-value is the probability of observing a mean as large or larger than 550 if the population mean really is only 500. The p-value is not the probability that the null hypothesis is true.
