DATA SET E Microprocessor Speed (MHz) and Power Dissipation (watts) (n = 14 chips) Chip Speed (MHz) Power (watts) 1989 Intel 80486 20 3 1993 Pentium 100 10 1997 Pentium II 233 35 1998 Intel Celeron 300 20 1999 Pentium III 600 42 1999 AMD Athlon 600 50 2000 Pentium 4 1300 51 2004 Celeron D 2100 73 2004 Pentium 4 3800 115 2005 Pentium D 3200 130 2007 AMD Phenom 2300 95 2008 Intel Core 2 3200 136 2009 Intel Core i7 2900 95 2009 AMD Phenom II 3200 125

obtain the regression equation: Y   =     X   +   

Explanation / Answer

as per the regreession analysis in excel,

Here,

Speed = Dependent variable

Power = Independent variable

And as per the above regression data

Intercept = -329.784

Coefficient of power = 29.051

Thus, regression equation is:

Speed = - 329.784 + 29.051*Power
