Problem 2 Eye Associates, which runs an optical lab, experienced substantial growth over the last decade. It purchased additional increments of lens-grinding equipment in relatively small units. Prior analysis of its data suggest that regression analysis is adequate to determine its future capacity demands Year Units (1,000) 2010 15 2011 15.5 2012 16.25 2013 16.75 2014 16.9 2015 17.24 2016 17.5 2017 17.3 2018 17.75 2019 18.1 At the start of 2020, Eye Associates has 8 machines and each is capable of grinding 2,500 lenses/year and it has been their practice to keep one machine in reserve, that is, they buy a new machine anytime forecast demand exceeds the capacity of 7 machines. a b. Please regress units sold on time (the year) What do you think of the appropriateness of the fit, please provide support for your conclusion? Use the results of your regression to forecast demand for the next 5 years Respecting the "reserve unit' requirement, when should EAS schedule the purchase of a new machine(s) over the next five years
