Question
Find the required linear model using least-squares regression.
The table below gives the total sales (in billions of dollars) for the aerospace industry.
Year 2006 2007 2008 2009 2010 2011
Total Sales 184.8|187.1 | 188.7|189.9|190.9| 191.7
(a) Find a linear model for the data with x = 6 corresponding to the year 2006.
(b) Assuming the trend continues, estimate the total sales for the year 2017.
(a) The linear model for the data is y = [ ]x + [ ].
(Round to two decimal places as needed.)
