The ultimate strength of a sample is the stress at which the sampleSelect the correct option remains underwater bends 180? breaks returns to its original shape when the stress is removed

is the breaking stress same as the ultimate tensile stress?

The average breaking strength of steel rods is required to be at least 35,000 psi. Based on historical information, the standard deviation of breaking strength is 1,500 psi. A random sample of 4 specimens had the strength: piece one was 32,000, piece two was 36,000, piece three was 34,000, and piece four was 34,500. Which of the following hypothesis tests would you conduct?a.One sample t Testb.One sample Chi-square Testc.One sample Z Testd.One sample F TestClear my choice

In compression, a prism of brittle material will break

A random sample of 4 specimens had the strength: piece one was 32,000, piece two was 36,000, piece three was 34,000, and piece four was 34,500. What will be null and alternate hypothesis in this case?a.H0: µ = 35,000 psi  and  H1: µ ≠ 35,000 psib.H0: µ ≥ 35,000 psi  and  H1: µ < 35,000 psic.H0: µ > 35,000 psi  and  H1: µ < 35,000 psid.H0: µ ≥ 35,000 psi  and  H1: µ = 35,000 psi
