A lumber company is making doors that are 2058.02058.0 millimeters tall. If the doors are too long they must be trimmed, and if the doors are too short they cannot be used. A sample of 2222 is made, and it is found that they have a mean of 2045.02045.0 millimeters with a standard deviation of 13.013.0. A level of significance of 0.10.1 will be used to determine if the doors are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the doors are either too long or too short
