Textbook Question
Chapter 1, Problem 16P
The tensile 0.2 percent offset yield strength of AISI 1137 cold-drawn steel bars up to 1 inch in diameter from 2 mills and 25 heats is reported as follows:
| Sy | 93 | 95 | 97 | 99 | 101 | 103 | 105 | 107 | 109 | 111 |
| f | 19 | 25 | 38 | 17 | 12 | 10 | 5 | 4 | 4 | 2 |
where Sy is the class midpoint in kpsi and f is the number in each class. Presuming the distribution is normal, what is the yield strength exceeded by 99 percent of the population?
