Question: Repeat Prob. 215 assuming the material to be cast iron. Repeat Prob. 215, Brinell hardness tests were made on a random sample of 10 steel

Repeat Prob. 2–15 assuming the material to be cast iron.
Repeat Prob. 2–15, Brinell hardness tests were made on a random sample of 10 steel parts during processing. The results were HB values of 230, 232(2), 234, 235(3), 236(2), and 239. Estimate the mean and standard deviation of the ultimate strength in kpsi.
