What is the null hypothesis, alternative hypothesis, and p value? What is an example of a hypothesis? What does hypothesis mean? What is an alternative hypothesis? What variable is predicted by the hypothesis? What is a scientific hypothesis?
Difference Between the Null Hypothesis and Alternative Hypothesis The null hypothesisrepresents the absence of an effect or difference, while the alternative hypothesisproposes a specific effect or change. In other words,the alternative hypothesis represents the opposite of the null hypothesis. The main d...
What does it mean if we reject the null hypothesis? Fill in the blank to answer/complete the statement. When you fail to reject the null hypothesis but the null hypothesis is in fact false, you have made a(n) ___ error. True or False: You do not accept the null hypothesis ...
Do you reject or fail to reject the null hypothesis? What does this mean in terms of the study? Are the 3 groups significantly different from one another in terms of their taste rating? Justify your answer by comparing the p-value with th...
When the two independent groups for comparison are assumed to have unequal variances, the effect size of the independent-sample analysis is measured by the mean difference. For more information, see PARAMETERS Subcommand (POWER MEANS INDEPENDENT command). POWER MEANS ONESAMPLE The new PRECISION ...
In most cases, we are looking to see if we can show that we can reject the null hypothesis and accept the alternative hypothesis, which is that the population means are not equal:HA: u1≠ u2To do this, we need to set a significance level (also called alpha) that allows us to either...
Answer to: Once you have conducted the hypothesis test, what are the additional assumptions required to validate the results of the hypothesis...
Suppose we conduct a hypothesis test and the null hypothesis is {eq}H_0: \mu \geq 45 {/eq}. What is the alternative hypothesis? Writing the Alternative Hypothesis: When performing a statistical test, regardless of its type, we first...
The t-test is a test used for hypothesis testing in statistics. Calculating a t-test requires the difference between the mean values from each data set, the standard deviation of each group, and the number of data values. T-tests can be dependent or independent. ...
If no real difference exists between the tested groups, called thenull hypothesis, the result of the ANOVA's F-ratio statistic will be close to one. The distribution of all possible values of the F statistic is the F-distribution. This is a group of distribution functions with two characteri...
