.
Decide which case values are better and why? (5 %)
Assume trend is zero for the 2012 years. Year Number
of sold cars
2012 107 2013 113 2014 150 2015 133 2016 151 2017 1
Based on least squared regression method find the
projections for the years 2021, 2022, and 2023. Plot
the number of sold cars versus years (points graph) and
show the trend line based on your projections. (5%).
