Calculation:If
Graph: The graph for the regression line and points are shown as,
The predicted attendance on opening day in 2012.

Answer to Problem 12PPS
The predicted attendance on opening day in 2012 will be 66352.
Explanation of Solution
Given: The opening day attendance at the North Carolina State fair for 2000 was 53331, for 2001 it was 47940, for 2002 it was 54036, for 2003 it was 61334, for 2004 it was 61289 and for 2005 it was 52201.
Calculation: The predicted attendance on opening day in 2012 can be obtained by plugging
