Sales of a video game released in the year 2000 took off at first, but then steadily slowed as time moved on. The table below shows the number of games sold, in thousands, from the years 2000–2010.
Year 2000 2001 2002 2003 2004 2005
Number Sold (thousands) 142 149 154 155 159 161
Year 2006 2007 2008 2009 2010 —
Number Sold (thousands) 163 164 164 166 167 —
A. Let x represent the time in years starting with x=1 for the year 2000. Let y represent the number of games sold in thousands.
I got log y=141.91242949 + 10.45366573In(x)
D. If you were to manipulate the data you could do the opposite regression of what you did in a) what is this regression formula?
E. Using the regression formula obtained in d) how many games will be sold in 2015? What did you do to the data from the table to obtain this second regression formula?
