Question
A lumberyard has a machine that is designed to cut deck boards to a length of 14 feet. The manager of the lumberyard is concerned that the machine is not cutting the boards the correct length. He takes a random sample of 17 boards and records their lengths. Do these data provide convincing evidence at the = 0.05 level that the mean length of the cut boards differs from 14 feet? Let = the true mean length of the deck boards.
- Data: 13.89, 13.90, 13.95, 13.98, 13.99, 14.0, 14.02, 14.05, 14.08, 14.1, 14.15, 14.18, 14.2, 14.21, 14.23, 14.25, 14.3
Based on the scenario, identify the appropriate hypotheses to use to conduct a significance test.
