Graph the 3-month T-bill interest rate (i3), the 10-year government bond interest rate (i10), and the CPI inflation rate (based on the % change in the CPI from one year earlier) on the same figure (or in two figures, one with i3 and inflation and the other with i10 and inflation), using monthly data since 2000. Make sure that the units are comparable. Just the graph in EXCEL is enough, no need to report the figures for each month.
