Question 9 3 pts Lockheed Martin Lockheed Martin, the defense contractor designs and build communication satellite systems to be used by the U.S. military. Because of the very high cost the company performs numerous test on every component. These test tend to extend the component assembly time. Suppose the time required to construct and test (called build time) a particular component is thought to be normally distributed, with mean equal to 15 hours and a standard deviation equal to 2.25 hours. To keep the assembly flow moving on schedule, this component needs to have a build time between 12.5 and 18 hours. Find the probability that the build time will be such that assembly will stay on schedule. 0.2253 0.1335 0.7747 0.9082
