## How To Find Distrubitoin When Null Hypothesis Is True

Disproving the Null Hypothesis. The Misconception. Although the null hypothesis cannot be proven true, it can be proven false. This is because science and hypothesis testing are …

- Hypothesis Testing Hypothesis testing allows us to use a sample to decide between two statements made about a Population characteristic. These two statements are called the Null Hypothesis and the Alternative Hypothesis. Definitions H0: The Null Hypothesis This is the hypothesis or claim that is initially assumed to be true. HA: The Alternative Hypothesis This is the hypothesis or claim which
- the frequencies one would expect if the null hypothesis were true. The power of a test refers to: the probability of rejecting the null hypothesis when it is actually false
- If the null hypothesis is true, then the F test-statistic given above can be simplified (dramatically). This ratio of sample variances will be test statistic used. If the null hypothesis is false, then we will reject the null hypothesis that the ratio was equal to 1 and our assumption that they were equal.
- The sampling distribution assumes that the null hypothesis is true. When we compare an obtained test statistic to the sampling distribution, we’re asking how likely it is that we would get that statistic if we were sampling from a population that has the null hypothesis characteristics (e.g., P = 0.50).
