This researcher is extremely focused on avoiding mistakes in concluding that this new treatment is effective when it really is not when conducting their research. What should this researcher do?

 a.set a low alpha level  

 b.set a high alpha level  

 c.set a low sample mean  

 d.set a high sample mean  

Solution

Option A
