I demonstrate how to perform a hypothesis test for the mean when sigma is unknown. The procedure for finding the p-value in the assigned book for the course that I teach uses the student t-distribution chart linked below. You can also use Excel or a graphing calculator to find the value - the steps for this can be googled ("How to find p-value with a TI-84 Calculator" or "How to find a p-value in Excel").
