Estmation of Traffic Flow
The following data give the number of vehicles (in millions) crossing the Brooklyn Bridge each ear for 10 years. Fit a cubic polynomial to the data and use the fit to estimate the flow in the year of 2020.
2009 2010 2011 2012 2013 2014 2015 2016 2017 2018
2.1 3.4 4.5 5.3 6.2 6.6 6.8 7 7.4 7.8
1) Plot this data set
2) Draw a curve (Year vs Vehicle flow (millions)) using regression.
