Question 167404: The table gives the median values of new privately owned U.S. homes for 1983 through 1997. In the table, t is the time (in years) with t=3 corresponding to 1983, and y1 and y2 are the median prices (in thousands of dollars) in the Northeast and the South, respectively.
T= 3, 4, 5, 6, 7, 8
Y1= 82.2, 88.6, 103.3, 125, 140, 149
Y2= 70.9, 72, 75, 80.2, 88, 92
T=9,10, 11, 12, 13
Y1= 159.6, 159, 155.9, 169, 162.6
Y2= 96.4, 99, 100, 105.5, 115
T= 14, 15, 16, 17
Y1= 169, 180, 186, 190
Y2= 116.9, 124.5, 126.2, 129.6
a) use the regression capabilities of a graphing utility to fit a cubic model to the median prices of homes in the Northeast.
b) Use the regression capabilities of a graphing utility to fit a cubic model to the median prices of homes in the South.
THANK YOU SO MUCH, IT MEANS A LOT! :)
