Sample size calculation

What is the null hypothesis?That adding Jedi Flow will be no more effective than thrombolysis alone in improving the mortality rate in acute MI.
What level do we want to avoid a type I error at? (pα)We set this to 0.05
What level do we want to avoid a type II error at? (pβ)We set this to 0.8
What is the “clinically important difference” we want to detect?3%
What is the mortality rate using thrombolysis alone?12%
