Doing a non-parametric test on Baseball stats/American versus National league batting. The question is: Is there a significance difference in the two leagues batting averages? I will need to know the Non-parametric test and which test to run?
Label each of the following situations "P" if it is an example of parametric data or "NP" if it is an example of nonparametric data. 1. A manufacturer produces a batch of memory chips (RAM) and measures the mean-time-between-failures (MTBF). The manufacturer then changes a manufacturing process and produces another batch
Differentiate between parametric and nonparametric tests Identify the data in the situations A-G as: + Numeric or Attribute Data + Parametric or Nonparametric + Briefly explain you choice Complete any four. Example: A manufacturer produces a batch of memory chips and measures the mean-time-between-failure (MTBF).

Do you have any pointers that will help me study more effectively? Thanks. By the way, this week we are working on Chi Square and Alternatives to t and F (The Mann-Whitney U Test, The Wilcoxon Matched-Pairs Signed-Ranks Test, Kruskal-Wallis One-Way ANOVA, Further testing after a Significant H). ------------------------
Nonparametric Hypothesis Test for real estate data. Step by step method for testing the hypothesis under 5 step approach is discussed here. Excel template for each problem is also included. This template can be used to obtain the answers of similar problems.
Using this question "Does the average selling price of a home with a pool differ from the average selling price of a home without a pool?" I need to conduct a nonparametric test performing the 5-step hypothesis test on the data. Data set attached. Be sure to include raw data tables and the results of the computations if you

Describe the requirements that must be met before an ANOVA test can be used. Discuss what the researcher should do if one of these requirements is not met.
A. What type of data is used with chi square analysis? b. What are the nonparametric tests that correspond to other two parametric tests?
Bring to mind a real-world situation or problem that would best be analyzed in the chi-square test of association. This would be a nonparametric procedure that requires different assumptions. For this situation or problem, please make sure that the following is addressed: Real-world situation or problem you selected to ad

In an effort to link cold environments with hypertension in humans, a preliminary experiment was conducted to investigate the effect of cold on hypertension in rats. Twelve rats were assigned at random to two groups (6 in a group), in which each group was exposed to a different environment. One group was held in a normal environ
Instructions: In all exercises, use a computer package (e.g., MegaStat, MINITAB) or show the calculations in a worksheet, depending on your instructor's wishes. If you use the computer, include relevant output or screen shots. If you do the calculations manually, show your work. State the hypotheses and give the test statistic a
