The best-fitting line for IMPORTS (U.S. imports of furniture, in $billions) and RATE (the interest rate on U.S. commercial paper) is: IMPORTS = 2.5 – 0.05 RATE. The slope of the line means that, on average, a 1% ["decrease", "increase"] in the U.S. commercial paper interest rate is associated with a ["2.5 $billion", "5 $billion", "50 $million"] increase in...
