9 OOO O 6 points This question uses negative marking. Which of the following statement(s) is a false description of your optimised process? When control engineers manage to minimise the standard deviations for all the process variables, the scrap cost will be minimised. When control engineers manage to set the standard deviations for all the process variables at zero, the scrap cost will be minimised. When control engineers manage to set all the process variables at the values you supplied in questions 1 to 4 above (assuming you supplied the correct answers), the scrap cost will be minimised. When control engineers manage to set all the process variables on average at the values you supplied in questions 1 to 4 above (assuming you supplied the correct answers), the scrap cost will be minimised. 10 5 points Risk Optimiser makes use of which of the following technique(s) when searching for optimum process condition? Mutations Second partial derivatives Random sampling OOOOOO First partial derivatives Crossover Path of steepest ascent/descent
