    Assistance for study hypothesis and stat analysis

    I require assistance for a study hypothesis and statistical analysis plan for the below. (1) Research question : To find time to stop bleeding with use of product. (2) Data Collection : Time take to stop bleeding will be captured with use of a stop watch. Eg. Patient 1= 5 minutes; Patient 2 =...
