a$)$Compute the Coefficient of Correlation Analysis.

B$)$Create a SCATTER PLOT that shows the value for R$2.$

C$)$Based on the correlation coefficient r and the result of the scatter plot, how would you describe the relationship between the frequency of warranty causes and their repair cost?

D$)$Create a PARETO CHART based on the cause frequency.

e$)$ Based on the Pareto chart, what are the most important causes of warranty issues that need to be addressed. Explain why$/$how you identified these causes.
