A lumber company is making boards that are 2979 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 34 boards is taken, and it is found that they have a mean of 2975.6 millimeters. Assume a population standard
deviation of 12. Is there evidence at the 0.05 level that the boards are either too long or too short?
Step 2 of 3: Find the P-value for the hypothesis test. Round your answer to four decimal places.
