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 a mean equal to 45 hours and a standard deviation equal to 6.75 hours. to keep the assembly flow moving on schedule, this component needs to have a build time between 37.5 and 54 hours. find the propability that the bulid time will be such that assembly will stay on schedule.
