Instructions: Choose one or more of the data sets $A-J$ below, or as assigned by your instructor. The first column is the $X$, or independent, variable and the second column is the $Y$, or dependent, variable. Use a spreadsheet or a statistical package (e.g., MegaStat or MINITAB) to obtain the simple regression and required graphs. Write your answers to exercises 12.32 through 12.47 (or those assigned by your instructor) in a concise report, labeling your answers to each question. Insert tables and graphs in your report as appropriate. You may work with a partner if your instructor allows it.
Is the sample size sufficient to yield a good estimate? If not, do you think more data could easily be obtained, given the nature of the problem?
