A lumber company is making boards that are 2599.0 millimeters tall. If the boards are too long they must be trimmed, and if they are too short they cannot be used. A sample of 23 boards is made, and it is found that they have a mean of 2600.3 millimeters with a standard deviation of 13.0. Is there evidence at the 0.05 level that the boards are either too long or too short
