Problem 62E
Consider the following information on ultimate tensile strength (lb/in) for a sample of n = 4hard zirconium copper wire specimens (from “Characterization Methods for Fine Copper Wire,” Wire J. Intl., Aug., 1997: 74–80):
Determine the values of the two middle sample observations (and don’t do it by successive guessing!).
ANSWER:
Solution :
Step 1 of 1:
Given the sample of size n = 4 hard zirconium copper wire specimens.
Our goal is:
We need to find the values of the two middle sample observations.
The mean and standard deviation are
