Homework Matlab 8 normcdt, normpdf, etc. Engineering Background: When concrete is being poured for a highway or a concrete building, the supervising engineer will typically collect some wet concrete for a slump test. In this test, the concrete is put into a conical container, which is then flipped over. The container is carefully removed, and the vertical subsidence of the concrete (the slump) is then measured (typically in mm.) The amount of slump is related to the ultimate strength of the concrete. Too much slump implies too much water in the mix, and the concrete will be weak. Too little slump implies too little water in the mix, and the concrete will be brittle. Either way the supervising site engineer can send bad concrete back to the concrete plant as inadequate. 3 4 6 Figure 1: How to do a slump test Assignment: You are given a set c would like to estimate probabilisti do these tests throughout the con ime is normally-distributed.
