Ray,
I attached the modified spreadsheet with additional column for calculating
the execution time of the
DEC3000. They are derived from dividing the VAX11/780 time with
the DEC3000 SPECRatio. You then
follows the same weighti*Timei calculation as column C. The sum of
all entries will be the weighted
arithmetic mean of DEC3000 Execution Time.
Same procedure is applied for the weight arithmetic means of
IBM and Intel Xpress machines.
Hope this help. Let me know if you still have question.
Edward

problem 1.11. I think I worked out the weights for the
VAX (part A)
correctly, however, my problem lies with part B and how to use
the chart to
derive what is wanted. I am not even sure what is wanted.
