HYR is building a sea defence wall and the construction contract specifies that HYR will be responsible for paying compensation if the sea wall is breached. Three designs for the wall are being considered. They cost differing amounts to build and the suitability of each (and therefore the likelihood of compensation pay-outs) will depend on the weather conditions anticipated. HYR's Board has decided to use expected values and will select the design with the lowest expected cost. The finance director has voiced concerns that HYR should be focused on achieving the best results if the worst happens. Which TWO statements concerning the decision are true? Solution A.By using expected values HYR are demonstrating a risk averse attitude. B.Expected values are particularly useful when evaluating this sort of one-off decision. C.The finance director is advocating the use of the maximin rule. D.Standard deviations could be used to measure the volatility of the possible outcomes
