17.1 The Beta II computer's electronic processing unit contains 50 components in series. The average reliability of each component is 99.0%. Using Figure 17.2, determine the overall reliability of the processing unit. 17.2. A testing process at Boeing Aircraft has 400 components in series. The average reliability of each component is 99.5%. Use Figure 17.2 to find the overall reliability of the whole testing process. 17.4 Robert Klassan Manufacturing, a medical equipment manufacturer, subjected 100 heart pacemakers to 5,000 hours of testing. Halfway through the testing, 5 pacemakers failed. What was the failure rate in terms of the following: a) Percentage of failures? b) Number of failures per unit-hour? c) Number of failures per unit-year? d) If 1,100 people receive pacemaker implants, how many units can we expect to fail during the following year
