So-and-so company manufactures microprocessors for the space agency. It expects So-and-so's microprocessors to provide between 3,000 and 3,600 hours of processing during their useful life.

So-and-so's process is such that the longevity of its microprocessors follows a normal law with an average of 3300 and a standard deviation of 65 hours of processing.
