Describe a Real-Life Situation for Hypothesis Test for Two Variances

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

1. Describe a 5-step hypothesis test for two variances for a particular claim related to your work or life environment. You need to state the claim, define the null and alternate hypothesis, identify the test significance and the test statistic, and state the decision rule that will be used. The decision rule may be based on critical values or on the p-value approach. You do not need to collect data and actually conduct the test calculations unless you wish to do so.

2. Describe a 5-step hypothesis test using any one of the nonparametric tests in your reading material for a particular claim related to your work or life environment. You need to state the claim, define the null and alternate hypotheses, identify the test significance and the test statistic, and state the decision rule that will be used. The decision rule may be based on critical values or on the p-value approach. You do not need to collect data and actually conduct the test calculations unless you wish to do so.

Real World problem: Identify variables, samples, t test, null and alternative hypothesis

Bring to mind a real-world situation or problem that could be addressed using an independent- or related-samples t test. do not need to use the SPSS to complete.

For this situation or problem:

Clearly identify the independent and dependent variables you would study.

Determine whether an independent-samples or related-samples t test is most appropriate and why.

Generate the statistical null and alternative hypotheses.

Describe what information the effect size would tell you that the probability value would not tell you.

Using realistic numbers for values of degrees of freedom, sample size, and t statistic, report hypothetical results in a few sentences.

So with this in mind take the real-world situation or problem you selected to address, the independent and dependent variables you would study, an explanation of whether an independent-samples or related-samples t test is most appropriate, the statistical null and alternative hypotheses, a description of what information the effect size would tell you that the probability value would not tell you, and your hypothetical results.
