**Hypothesis Testing:**

Hypothesis Test, also known as Statistical Hypothesis Test is a method of statistical inference. Since it is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables, it is also referred to as confirmatory data analysis. The hypothesis testing for population mean analyses the results of the null hypothesis and the alternative hypothesis of a population. Hypothesis testing is one of the final analysis of statistical data.

Use this free sample and population statistics calculator to perform a statistical hypothesis test for the given population mean. This **online hypothesis testing calculator for population mean** helps you to perform the two-tailed and one-tailed statistical hypothesis testing.

#### Example:

If you are performing one-tailed test for the sample mean of 20, population mean of 15, the size of the population of 5, SD of 25 and the significance level of -10, then you will get the below values as result.

#### Solution 1 :

T-score is 0.44721

#### Solution 2 :

P-value is 0.6726

#### Decision :

P-value > -10 ( Significance level). Hence, H0 is not rejected.

H0 is Null Hypothesis.
