9. (a) The masses, in grams, of plums of a certain kind have the distribution N(55, 18). (i) Find the probability that a plum chosen at random has a mass between 50.0 60.0 grams. (ii) The heaviest 5% of plums are classified as extra large. Find the minimum mass of extra large plums. (iii) The plums are packed in bags, each containing 10 randomly selected plums. Find the probability that a bag chosen at random has a total mass of less than 530 g.
