Tensile tests of a 3D printed material show that the average yield strength of that material is about 800 MPa with a standard deviation of 40 MPa. Due to the variations of the process parameters, the yield strength can vary, and historical data show that yield strength of the material follows a uniform continuous distribution. Answer questions 1a to 1e using this information. 1.If yield strength of the material is uniformly distributed between 730.72 to 869.28, what is the expected...
