Question 4 Between 2000 and 2010, the use of opioids was exploding in the USA. We use MME (Morphine Milligram Equivalents) as a measure of doses used. It went from 91 billion doses in 2000 to a level 159% higher in 2009. Using the linear model to estimate consumptions, what would be the equivalent annual growth rate that occurred between 2007 and 2009? Give your answer in % and if needed, round your answer to 2 digits after the decimal point.
