Alternative Hypothesis Example: Example:“Plants grow better when given filtered water compared to tap water.” Example:“Professional musicians are more likely to have higher auditory memory than non-musicians
Rejecting or failing to reject the null hypothesis is determined by the p-value of the test that is run. Generally, if the p-value is below the alpha...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Ou...
If you have aP-value, or are asked to find a p-value, follow these instructions to support or reject the null hypothesis. This method works if you are given analpha levelandif you arenotgiven an alpha level. If you are given aconfidence level, subtract from 1 to get the ...
The hypothesis statement in this question is that the researcher believes the average recovery time is more than 8.2 weeks. It can be written in mathematical terms as: H1: μ > 8.2 Next, you’ll need tostate the null hypothesis.That’s what will happen if the researcher iswrong. In the...
For the examples below, the alternative hypothesis would be: Students score an average that is not equal to seven. The mean annual return of a mutual fund is not equal to 8% per year. In other words, the alternative hypothesis is a direct contradiction of the null hypothesis. ...
Any information that is against the stated null hypothesis is taken to be the alternative hypothesis for the purpose of testing the hypotheses. In such a case, the alternative hypothesis is “the mean annual return of ABC Limited is 7.5%.” ...
However, it is important to note that in this empirical work the unit root is set up as the null hypothesis testing is carried out ensures that the null hypothesis is accepted unless there is strong evidence against it. Therefore, an alternative explanation for the common failure to reject a...
(a) Null Hypothesis (H0):The factor causes no difference in means within or between groups. If means are symbolized withµ, theNull Hypothesisconcludes:µ1= µ2= µ3…. = µN. (b) Alternative Hypothesis (H1):the factor causes significant differences in the means. TheAlternative Hy...
How to interpret the p-value to get the conclusion? P-Value: The P-value is a probability value of a test statistic. It is used to identify the correct statement of the null and the alternative hypothesis about the population parameter by comparing P-value to the level of significance. ...
But apart from these variations, we are usually interested in what is called the “alternative hypothesis” and, in contrast to that, the “null hypothesis”. If you think these two should be listed the other way round, then you are right, logically speaking—the alternative should surely ...
