Hello James, I also need help with Hypothesis testing as well. I need to know what website to use for a calculator to solve the problem you helped with. I am in the process of looking for a tutor. I am taking basic biostatistics as a nursing prerequisite. I am a senior in college and I am having a hard time grasping the concept of what is being asked. Math is my weakest subject. I am past my mid semester and as I moving ahead things are becoming more complicated. My major is nursing. I have an associates degree in nursing and working on my BSN degree.
