A carpenter is making doors that are 2058.0 millimeters tall. If the doors are too long they must be trimmed, and if they are too short they cannot be used. A sample of 11 doors is made, and it is found that they have a mean of 2069.0 millimeters with a standard deviation of 19.0. Is there evidence at the 0.1 level that the doors are either too long or too short? Assume the population distribution is approximately normal. Step 4 of 5 : Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
