The alternative hypothesis is effectively the opposite of a null hypothesis. Thus, they are mutually exclusive , and only one can be true. However, one of the two hypotheses will always be true.

Null hypothesis vs. hypothesis, which is the right choice? When you get into the different methods of analyzing data, there is no shortage of tools at your disposal. Understanding the difference ...

Step 1: Based on the null and alternative hypotheses and given alpha, find a critical z-value (or z-values). Remember that alpha is the tail probability (in the right tail for the given alternative ...

Hypothesis testing provides a method to reject a null hypothesis within a certain confidence level. If you can reject the null hypothesis, it provides support for the alternative hypothesis.

They developed an approach called hypothesis testing in which the p value serves only to help the researcher make an optimised choice between the null hypothesis and an alternative hypothesis: If ...

The null hypothesis is H0: Die is fair (p 1 =p 2 =p 3 =p 4 =p 5 =p 6 =1/6 where pi is the probability of side i on the die), and the alternative hypothesis is Ha: Die is not fair (Not (p 1 =p 2 =p 3 ...
