The x and the y variable in the table below are correlated. Determine the ‘R’ value, and then determine the regression equation.
\n" ); document.write( "x y
\n" ); document.write( "16.66 28.34
\n" ); document.write( "20.70 37.38
\n" ); document.write( "24.33 45.52

\n" ); document.write( "\n" ); document.write( "---------------------
\n" ); document.write( "Hopefully you have a calculator or software available to do this calculation.
\n" ); document.write( "I used a TI with LinReg function to get the following:
\n" ); document.write( "y=2.1565x - 6.0404
\n" ); document.write( "R = 0.9750
