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.” 2. Null Hypothesis (H0) The null hypothesis is the “no effect” hypothesis. It’...
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%.” ...
(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...
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 ...
The series is expressed as the sum of deterministic trend, random walk, and stationary error, and the test is the LM test of the hypothesis that the random walk has zero variance. The asymptotic distribution of the statistic is derived under the null and under the alternative that the series...
The null hypothesis states that the portfolio’s returns are equivalent to the S&P 500’s returns over a specified period, while the alternative hypothesis states that the portfolio’s returns and the S&P 500’s returns are not equivalent—if the investor conducted aone-tailed test, the alternati...
