- Thanx in advance to any direct responses or references to the following
- problem I have:
-
- Assume this hypothetical situation - A paper mill produces a roll of paper
- 5 miles long and 50" wide and measures the thickness of the paper at the
- plant. The measurements are taken throughout the roll to represent the entire
- roll.
-
- Some people want to do an experiment at the customers plant to see if the
- customers thickness measurements relate to the producer's thickness
- measurementsAssuming that in the customer's plant, the method of measurement is
- to take
- equal size pieces of paper throughout the roll and measure the thickness of
- each, how many pieces of paper need to be sampled in order to "represent"
- the whole roll AND to try and see if there is any correlation between the
- different measuring systems? (the producer's method of measurement is an
- on-line continuous reading by a high speed gauge).
-
- What information is needed for this experiment?
