Hypothesis testing

• Another way of statistical inference in which we
  want to ask a question like
  
  
  • How likely is the mean systolic blood pressure
    from a sampled population (e.g. biomedical
    researchers) the same as those in the general
    population?
    
    
    • i.e. researchers = general?
    
    
    
    
  
  
  • Is the difference between 1 and 2 statistically
    significant for us to reject the hypothesis that their
    corresponding u 1 and u 2 are the same?
    
    
    • i.e. male = female?
