   If both researchers draw a sample of size 100, which study achieves the greatest power?

   
   
   1. FALSE: The power is equal in both cases because the samples are of equal size.
   2. FALSE: The power is equal in both cases because the samples used $\alpha$’s are equal.
   3. FALSE: Research II
   4. TRUE: Research I
