The effectiveness of a blood-pressure drug is being investigated. How might an experimenter
demonstrate that, on average, the reduction in systolic pressure is 20 or more (has to do with
estimation)?
Solution
He will take a sample of some people's systolic pressure before and after admitting
the drug and then test for mean=mu1-mu2>20 at the required level... If it is not rejected then he
can say that the reduction is 20 or more at that level.....
