Chapter 1, Problem 14P
Determinations of the ultimate tensile strength Swt of stainless-steel sheet (17-7PH, condition TH 1050), in sizes from 0.016 to 0.062 in. in 197 tests combined into seven classes were
| Swt (kpsi) | | 174 | 182 | 190 | 198 | 206 | 214 | 222 |
| f | 6 | 9 | 44 | 67 | 53 | 12 | 6 |
where Swt is the class midpoint and f is the class frequency. Estimate the mean and standard deviation.
