which statistical should I use if I want to perform the appropriate test to assess the research question: “Is there a difference in degree of pain during maximal activity while on Motrin compared to placebo?” and assume the data are NOT normally distributed and CLT does not apply to the data.
We consider a nonparametric Mann-Whitney test (aka Wilcoxon test) for independent two samples, although analogous tests are possible for paired two samples.
Answer is Mann-Whitney Test

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all. Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...

Part 3: Which Test Should You Use? scenarios. Your task is to determine which statistical test is most appropriate a), and to explain why you chose that statistical test (part b). Consider things variables, scores vs. frequencies, number of groups, and what we know (or don not Below are 8 research Directions: Below are8 to test each research like continuous vs. nominal know) about various populations Your which statistical test to use.

Consider each of the scenarios below. For each statement, decide which statistical procedure is most appropriate. One-sample hypothesis test for a single proportionOne-sample confidence interval for a single proportionTwo-sample hypothesis test for the difference in proportionsTwo-sample confidence interval for the difference in proportions Chi-square test for multiple categories of a single variable Chi-square test of independence of 2 categorical variables One-sample hypothesis test for a single mean One-sample confidence interval for a single mean Two-sample hypothesis test for the difference...
In Ezercises 12.85 12.94, use Procedure 12.2 on page 557 to perform an appropriate hypothesis test. Be sure to check the conditions for using that procedure 12.92 Delayed Perinatal Stroke. In the article "Prothrombotic Factors in Children With Stroke or Poren cephaly" (Pediatrics Journal, Vol. 116, Issue 2, pp. 447-453), J. Lynch et al. compared differences and similarities in children with arterial ischemic stroke and porencephaly. Three classification categories were used: perinatal stroke, delayed perinatal stroke, and childhood stroke. Of...

The

Help with this page is greatly appreciated. I dont understand
how to show a full diagram. Thanks in advance :)
The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...
Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
need help matching these please. thanks!
