(a) Find the probability that a single claim, chosen at random, will be less than $490. ANSWER: (b) Now suppose that the next 70 claims can be regarded as a random sample from the long-run claims process. Find the probability that the average of the 70 claims is smaller than $490. ANSWER: (c) If a sample larger than 70 claims is considered, there would be chance of getting a sample with an average smaller then $490. (NOTE: Enter "LESS", "MORE" or "AN EQUAL" without the quotes.)
