I have several problems dealing with hypothesis, h_o, h_a, and what not... Couple questions that Im unclear about... 1. How do I determine whether a a hypothesis is a left or right tailed test? Is this determined with the h_o or h_a? 2. Rejecting or failing to reject a hypothesis... How do I know which one to choose...also does it matter if the test is right or left tailed? 3. How is a conclusion drawn? Help is so very much appreciated!!!!!!
