Nightingale | Week 12 Thurs Q&A | Hypothesis Test for Mean, Sigma Known (TI-84)

This shows a hypothesis test for a population mean when sigma is known. This particular question uses the p-value method to run the test, however, the problem walks you through finding the p-value using normalcdf (the old school way). Therefore, we find the p-value using both normalcdf and TI-84 calculator trick. This is #4 on Section 9.2 Known Standard Deviation from MyOpenMath assignments.
