  1. In an effort to check the quality of their cell phones, a manufacturing manager decides to take a random sample of 10 cell phones from yesterday’s production run, which produced cell phones with serial numbers ranging (according to when they were produced) from 43005000 to 43005999. If each of the 1000 phones is equally likely to be selected:

    1. What distribution would they use to model the selection?

    2. What is the probability that a randomly selected cell phone will be one of the last 100 to be produced?

The manager of a manufacturing plant claims that the average diameter of a particular product is 5.0 millimeters. A quality inspector, however, will not accept more than 5 parts out of 1000 to have diameter 5±0.027 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each. It is known that the population standard deviation is σ = 0.1 millimeter. Based on the sample information, how many parts per...
