Questions-3: Consider the following data on real GDP per capita in Canada: Year Per Capita Real GDP 1950 14 339 1960 17 351 1970 23 790 1980 30 732 1990 35 868 2000 43 288 2010 46 406 2011 47 554 2012 47 741 2013 48 066 2014 48 780 a) Using Excel, calculate the percentage growth rates in real GDP per capita in each of the years 2011 through 2014, from the previous year. (5 Points) b) Now, instead of calculating the annual percentage growth rates in the years 2011 through 2014 directly, use as an approximation: |100x(In(yt)-In(yt-1)) where yt is real per capita GDP in year t. How close does this approximation come to the actual growth rates you calculated in part (a)? (5 Points)
