On an assembly process the length of a particular part is supposed to be 0.45 cm long, but sometimes it's shorter than that and sometimes it's longer. In fact, its standard deviation is calculated as 0.025 cm. A single sample is taken from this process and the length is measured with a micrometer as being 0.39565 cm long. What is the probability that a single part will be this long or longer, if the production process is in control?
