Concerning the linear regression results from Excel. I have just analyzed
the data (transposing the columns) using Excel Ver. 7.0 in Win95. I get
slope = 4.75200
intcp = 1.1102..E-16
Using the spreadsheet to implement the standard least squares algorithm
(Baird, Experimentation), I get the SAME SLOPE and
intcp = 1.05736E-16
Using Vernier's Graphical Analysis for Windows, I get the SAME SLOPE and
intcp = 0.0000
