One manufacturer has stated in the technical data of their bolts that the bolts are between 2.77 centimeters and 2.82 centimeters in diameter. It follows from the manufacturing method of the bolts that their diameter follows a normal distribution with an expected value of 2.79 cm and a standard deviation of 0.013 cm. What proportion of the bolts do not meet the definition of diameter given in the technical data?
