A large population of metal rods have an average diameter of .943 inches with a standard deviationof .001 inches. The engineeringspecification for the rods requires that they be between .941 and .944 inches. Using the standardized normal table, determine the percentage of the population that should meet the requirement. Draw a normal distribution, and indicate the area under the curve that represents your answer.

This solution finds the probability that a randomly selected observation from a normal distribution falls between two points. The probability is represented by the area under a normal curve.
