Does failing to **reject** the **null** hypothesis mean the **null** hypothesis is true? In a similar way, a failure to **reject** the **null** hypothesis in a significance **test** does not mean that the **null** hypothesis is true.It only means that the scientist was unable to provide enough evidence for the alternative hypothesis.As a result, the scientists would have reason to **reject** the **null** hypothesis.

**Statology.org** **DA:** 17 **PA:** 26 **MOZ Rank:** 61

- In hypothesis testing, we want to know whether we should
**reject**or fail to**reject**some statistical hypothesis - To make this decision, we compare the p-value of the
**test**statistic to a significance level we have chosen to use for the**test** - If the p-value is less than the significance level, we
