A manufacturer uses electrical fuses in an electronic system. The fuses are purchased in large lots and tests sequentially until the first defective fuse is observed. Assume that the lot contains 4% defective fuses. Round to the nearest thousandths. What is the probability that the first defective fuse will be the fifth fuse tested? Find each of the following for the number of fuses tested until the first defective fuse is observed. mean? variance? standard deviation?
