I regressed the Money Supply on Reserves using data from Alan Greenspan's time as Fed Chairman, 1987 to 2006. You may recognize this regression from this week's assignment. The table below shows the regression results. lower upper coefficient std err t-stat p-value 95% 95% Intercept 5,602 53.05 108.48 10 5651 5859 Reserves -76.7 2.4862 -32.19 0 -84.9 75.1 Estimate the average value of the money supply when bank reserves are 20 billion dollars. (Note: all numbers are presented in billions. In other words, you enter 20 into the equation, not 20,000,000,000. Enter your answer rounded to two decimal places, again in billions.)
