Dear your satisfaction is more important, I provided answers with detailed explanation. If you are satisfied with my explanations please THUMBS UP.. Thanks inadvance for your support dear....

We can conduct Wilcoxon Signed Rank Test here.

Null hypothesis Ho : Two population medians are identical

Alternative hypothesis H1 : They are different

Full calculation with detailed steps are given below as an image.

Decision: Since the test is not significant,i.e, p value > 0.05 , we have no sufficient evidence to Reject Null Hypothesis

Conclusion : At 95% confidence level we conclude that two population medians are identical

My classmate asked if they are understanding the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation. Does this explain how you would evaluate the variation and other methods to ensure that the data are appropriate to use for the test correctly. Within Group variations are variations are caused by the differences inside of the individual groups. No matter the amount of individuals groups there are, the values are not all the same. The qualities inside of the values will not...

Does this describe the difference between Between-Treatments (Groups) and Within-Treatments (Groups) variation? Why? or Why not? The concept of a between-treatments estimate of Ơ2 and showed how to compute it when the sample sizes were equal. This estimate of Ơ2 is called the mean square due to treatments and is denoted MSTR. The numerator is called the sum of squares due to treatments and is denoted SSTR. The denominator, k – 1, represents the degrees of freedom associated with SSTR....
