Which of the non-parametric test for ordinal data is the best to use in the given scenario?
An experiment was conducted to compare the strengths of two types of elastic bandages: one a standard bandage of a specified weight and the other the same standard but treated with a chemical substance. Ten pieces of each were randomly selected from production. Does the treated bandage tend to be stronger than the standard?

A competency test is modified so that the proportion of test-takers that pass is more than 75%. A simple random
sample of test-takers is collected to determine if the proportion of passers is greater than 75%. The results of the
sample are shown below.

- Q5) An article in the ACI Materials Journal (Vol. 84, 1987, pp. 213–216) describes several experiments investigating the rodding of concrete to remove entrapped air. A 3-inch & 6-inch cylinder was used, and the number of times this rod was used is the design variable. The resulting compressive strength of the concrete specimen is the response. The data shown is posted on BruinLearn Week 2: A. Is there any difference in compressive strength due to the rodding level? Use (α= 0.05). B. Find the P-value for the F statistic in part (a). C.

You recruit 60 subjects, assigning 20 each to either one of two dietary interventions or to maintain their normal diet. You measure body weight before and after the intervention and calculate the change in body weight (post minus pre weights).
