Let's focus on the relationship between the average debt indollars at graduation (AveDebt) and the in-state cost per yearafter need-based aid (InCostAid).
a) Does a linear relationship between InCost Aid and AveDebtseem reasonable? Explain.
b) Are there any unusual cases in this sample? If yes, statewhich ones they are and how they may be affecting the least-squaresmodel fit.
