(a) The current particulate standard for diesel car emission is 0.6 g/mi with standard deviation 0.3 g/mi. It is hoped that a new engine design will reduce the emissions to a level below this standard. Using n = 20 samples and critical region defined as x < 0.5 g/mi, (i) find the probability the diesel car does not emit 0.6 g/mi when it actually does. (ii) find the probability the diesel car emit 0.6 g/mi when it actually emit 0.4 g/mi. (iii) calculate the power of the test.
