How is the p-value used in hypothesis testing?
In the p-value approach, the test statistic is used to calculate a p-value. If the test is a lower tail test, the p-value is the probability of getting a value for the test statistic at least as small as the value from the sample.
How to calculate the formula for hypothesis testing?
We will also need to calculate the test statistic to be able to reject the hypothesis testing. The formula for the test statistic is represented as follows, T= µ/(s/√n)
How to test hypothesis in two tailed test?
In a two-tailed test, the p-value is the probability of getting a value for the test statistic at least as unlikely as the value from the sample. To test the hypothesis in the p-value approach, compare the p-value to the level of significance. If the p-value is less than or equal to the level of signifance, reject the null hypothesis.
Which is the formula for the test statistic?
The formula for the test statistic is represented as follows, T= µ/(s/√n) Detailed Explanation. It has two parts one is known as the null hypothesis and the other is known as the alternative hypothesis. The null hypothesis is the one that the researcher tries to reject.
