4. An engineer wants to find an estimate of a specific concrete tension strength and takes 5 repeated measurements using a UTM machine obtaining 52, 47, 51, 53, and 49 MPa. a) (5 pts) What is the tension strength of the concrete? b) (5 pts) Estimate the uncertainty in the measurement c) (5 pts) The UTM is recalibrated so the bias is negligible, a new sample is measured to be 55.1 MPa. How does this last measurement should be expressed?
