A carpenter is making doors that are 2058.0 millimeters tall. Ifthe doors are too long they must be trimmed, and if they are tooshort they cannot be used. A sample of 36 doors is made, and it isfound that they have a mean of 2070.0 millimeters. Assume thestandard deviation is known to be 26.0. Is there evidence at the0.10 level that the doors are too long and need to betrimmed?
Step 1. State the hypothesis:
Step 2. Find the value of the z test statistic. (Round youranswer to 2 decimal places.)
