(a) Use a graphing calculator to fit a regression line to the data in Exercise 62.
In Exercise 62
Year, x Percentage of Deaths
Followed by Cremation, y
2005, 0 .............................................. 32.3%
2006, 1 ........................................ 33.6
2007, 3 ........................................ 34.3
2008, 4 ........................................ 35.8
2009, 4 ........................................ 36.9
(b) Estimate the percentage of deaths followed by cremation in 2013 and compares the result with the estimate found with the model in Exercise 62.
(c) Find the correlation coefficient for the regression line and determine whether the line fits the data closely. |
