Problem 8. The partial credibility approach is applied to a dataset of 500 claim amounts. It is assumed that the claim amount distribution is uniform on the interval [0, 0). The full credibility standard is to be within 5% of expected claim amount 99% of the time. The partial credibility factor Z is found using a normal approximation, After 300 additional claim amounts are recorded, the claim amount distribution is revised to be uniform on the interval [0, 1.60]. The revised partial credibility factor Z is found. Find the ratio Z/Z
