Question: The engineering specifications provide that a gasket should be between 395 mm and 405 mm, otherwise a gasket is defective. Assuming the process is working

The engineering specifications provide that a gasket should be between 395 mm and 405 mm, otherwise a gasket is defective. Assuming the process is working correctly; find the probability that a randomly selected gasket is not defective. Use Excel's built-in function for the Normal distribution to answer the question.
