Consider the following information on ultimate tensile strength (lb/in) for a sample of n = 4 hard

Question:

Consider the following information on ultimate tensile strength (lb/in) for a sample of n = 4 hard zirconium copper wire specimens (from "Characterization Methods for Fine Copper Wire," Wire J. Intl., Aug., 1997: 74-80):

x̅ = 76,831

s = 180

Smallest xi = 76,683

Largest xi = 77,048

Determine the values of the two middle sample observations (and don't do it by successive guessing!).
