In hypothesis testing, we set a null hypothesis (lets say mean x = 10), and then using a sample, test this hypothesis. After testing the hypothesis, we get a result (lets say x = 12). Now with p value, we obtain a probability that given than the population mean was 10, what is the probability that we get a sample mean of 12. kevin york jr. 23 of st. paul

"All statistical tests have a null hypothesis. For most tests, the null hypothesis is that there is no relationship between your variables of interest or that there is no difference among groups. For example, in a two-tailed t test, the null hypothesis is that the difference between two groups is zero.
