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:
Answer :
Step 1 of 2 :
Given, on ultimate tensile strength (lb/in) for a sample of n = 4 hard zirconium copper wire specimens
= 76,831, s = 140, smallest
= 76,683 and largest
= 77,048.
The claim is to find the values of the two middle sample observations
Let, =
-
= - 76,831
Then , =
-
= 76683 - 76,831
= -148
And =
-
= = 77048 - 76,831
= 217
Then, =
- 76831 = 0
So, +
= -(
) = -69
Let, s =
180 =
= 3(180
= 97200
