The following table shows the avg. room rate (in dollars) for the United States from 1999 to 2001: YEAR RATE 1999 $66.65 2000 $ 70.93 2001 $ 75.31 2002 $ 78.62 2003 $81.33 2004 $ 85.89 2005 $ 88.27 (A) Use a graphing utility to plot the data as a scatterplot. (B) Use your graphing calculator to find a linear model of the data and sketch it in the above viewing window. (C) Use your graphing calculator to find a quadratic model of the data and sketch it in the above viewing window LINEAR QUADRATIC a = 3.6 a = -0.11 667 b = b = 470.73 3 -474729 0571 r = 0.997 - r = 0.9970539232 (D) Which of the models has the higher correlation and what is that correlation? BETTER MODEL: Very Strong Strong Good Weak No Correlation Correlation Correlation Correlation Correlation (E) Using the better model calculate avg. room rate (in dollars) for the United States in 2014. -7129.057
