As part of an investigation into the collapse of the roof of a building, a testing laboratory is given all the available bolts that connected the steel structure at 3 different positions on the roof. The forces required to shear each of these bolts (coded values) are shown in Table Q4. Construct a hypothesis and perform an analysis to test whether the differences among the sample means at the 3 positions are significant at the 0.05 level of significance.
