std = sqrt(0.5*(0.5)/1316) =0.01378

z=(0.3-0.5)/0.01378 = -14.51

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.
