a) (4 points) Use the Excel sheet 'MeasureGDP' to calculate nominal GDP, nominal growth, real growth, and GDP Deflator inflation for 2018-2020.

b) (3 points) Holding all quantities fixed, do nominal prices matter when determining how much was produced in real terms using our chain-weighting algorithm? (Hint: Recall that our measure uses nominal prices as relative weights)

c) (3 points) Holding all quantities fixed, should nominal prices matter when determining how much was produced in real terms (real GDP)? In other words, do you find the result from b) desirable? Why or why Not
