Question: Ted manufactures bolts. They are supposed to average 2 inches long. If they are too long or too short (on average) I must adjust my machinery. A random sample of 100 bolts yields a sample mean of 1.9 inches with sample standard deviation of .5 inches. Is there evidence to conclude (at the .05 level of significance) that I should adjust my machinery? Perform an appropriate hypothesis test. Express results in a way a machinist might understand.
