QUESTION:

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
