Question: A factory delivered a truck-load of male fittings to your small assembly line where you will use these male fittings with your female fittings (male fittings are inserted inside a female fitting within acceptable looseness or tightness) on a certain project. You know that all of your female fittings have a standard deviation of 95 millimeters. You took a sample of 20 male fittings and found a variance of 8100 millimeters. Upon performing a hypothesis test (show your work) will you accept the delivery or will you return it to the supplier as non-acceptable considering that you only tolerate 5% error? What can you say about a p-value for this test?
