The table below provides data from the International Coffee Organization on green coffee bean quantities and prices. For each year from 1991 to 2019, the columns provide the quantity produced (in thousands of 60Kg bags/year) and average price (in US cents/lb). Copy the data into a spreadsheet. Make a scatter plot and run a regression of price versus quantity. Which of the responses is true?

O A regression of price on quantity gives us an unbiased estimate of the inverse demand curve for coffee.
O A regression of price on quantity gives us an unbiased estimate of the supply curve for coffee.
O Between 2001 and 2011, quantity and (inflation-adjusted) price both increased considerably, suggesting a
shifting of the demand curve was dominant during that period.
O Between 2011 and 2019, quantity increased and (inflation-adjusted) price decreased considerably, suggesting
a shifting of the demand curve was dominant during that period.
