1. Following the explosion of the 25th space shuttle flight‚ which was caused by an O-ring failure in one or more of the booster rockets‚ data from the previous 24 flights were studied. The Temperature (F) at the time of launch and whether or not there was evidence of O-ring failures for each of the previous 24 shuttle flights was determined for each flight. A logistic regression relating the Failure of O-rings to the Temperature was obtained with the following result: Estimate Std. Error z value Intercept

. 2. Explain why a product or system might have an overall reliability that is low even though it is comprised of components that have fairly high reliabilities. 4. A product engineer has developed the following equation for the cost of a system component: C _ (10 P ) 2 ‚ where C is the cost in dollars and P is the probability that the component will operate as expected. The system is composed of two identical components‚ both of which must operate for the system to operate. The engineer
