What is the conclusion if you reject the null hypothesis?
Because we fail to reject the null hypothesis, we conclude that there is not sufficient evidence to support a conclusion that the population mean is greater than 166.3 lb, as in the National Transportation and Safety Board’s recommendation.
How do you reject a null hypothesis in a two tailed test?
- You reject the null hypothesis if the z-score is large, which means that the p-value is small.
- If you reject a hypothesis at the 5% significance level, p < . 05, hence you will reject that hypothesis at the 10% significance level.
- If you fail to reject a hypothesis at the 5% significance level, p > .
What are the two possible conclusions of a hypothesis test?
There are only two statistical conclusions to make at the end of a hypothesis test: “we reject H0” or “we fail to reject H0.” The statistical conclusions never deal with the alternative hypothesis H1. Moreover, we never say that, “we accept H0.” It is either, “we reject H0” or “we fail to reject H0.”
What is your basis in rejecting the null hypothesis?
When your p-value is less than or equal to your significance level, you reject the null hypothesis. The data favors the alternative hypothesis. Your results are statistically significant. When your p-value is greater than your significance level, you fail to reject the null hypothesis.
What happens if we reject the null hypothesis?
If the null hypothesis is rejected, then an exact significance level is computed to describe the likelihood of observing the sample data assuming that the null hypothesis is true. The exact level of significance is called the p-value and it will be less than the chosen level of significance if we reject H 0.
What should be the final conclusion in a hypothesis test?
Wording Final Conclusions in Hypothesis Tests Some key points: • Never conclude a hypothesis test by saying either “reject the null hypothesis” or “fail to reject the null hypothesis.” Always make sense of the conclusion by stating it with simple nontechnical wording that addresses the original claim.
What makes a hypothesis a 2 tailed test?
So if the alternate hypothesis is written with a ≠ sign that means that we are going to perform a 2-tailed test because chances are it could be more than 100 or less than 100 which makes it 2-tailed. So, after stating the Null and Alternative hypothesis, it’s time to move to step-2 which is: 2. Choose the level of Significance (α)
Where does the null hypothesis lie on the curve?
So, if you look at the curve, the value of 2.89 will definitely lie on the red area towards the right of the curve because the critical value of 1.96 is less than 2.89. As the value lies in the rejection region, we could reject the Null hypothesis.
