In a regression analysis involving 27 observations, the following estimated regression equation was developed.
At the .05 significance level, can we conclude that the guideline is still reasonable?
Suppose there are two samples of size 6 and 7, with a rank sum of 58 in the sample of size 6. Using the Wilcox on rank-sum test, evaluate the significance of the results, assuming there are no ties.
Suggest a target population. Who, exactly, are the "students" in question? Suggest a choice of sampling method and comment on why you have made this choice.
