Gold and other precious metals have traditionally been considered a hedge against inflation. If this is true, we would expect that a fund made up of precious metals (gold, silver, platinum, and others) would have a strong positive relationship with the inflation rate. To see whether this is true, a statistics practitioner collected the monthly CPI and the monthly precious metals subindex, which is based on the prices of gold, silver, platinum, etc., for the years 1975 to 2008. These figures were used to calculate the monthly inflation rate and the monthly return on the precious metals subindex. Use a graphical technique to determine the nature of the relationship between the inflation rate and the return on the subindex. What does the graph tell you?
