Problem 2BSC

Freshman 15?For the matched pairs listed in Exercise,identify the following components used in the Wilcoxon signed-ranks test: a.?Differences?d b.?The ranks corresponding to the nonzero values of |d? | c.?The signed ranks d.?The sum of the positive ranks and the sum of the absolute values of the negative ranks e.?The value of?T f.?The critical value of?T?(assuming a 0.05 significance level in a test of no difference between September weights and April weights) Exercise Wilcoxon Signed-Ranks Test for Freshman 15?The following table lists some of the weights from Data Set 4 in Appendix B. Those weights were measured from college students in September and later in April of their freshman year. Assume that we plan to use the Wilcoxon signed-ranks test to test the claim of no difference between September weights and April weights. What requirements must be satisfied for this test? Is there any requirement that the populations must have a normal distribution or any other specific distribution? In what sense is this Wilcoxon signed-ranks test a “distribution-free test”?

Step-by-Step Solution:

Solution 2BSC Step 1 Now,we use the second approach to perform sign test. Then 2nd approach method suggest indicates to treat half of the 0s as positive and half as negative signs. The values are: The total subjects are 106 where 68 had temperatures below 98.6°F , 23 had temperatures above 98.6°F and 15 had temperatures equal to 98.6°F. Check the claim that the median is less than 98.6°F.
