I am confused about this stats problem

Suppose you are interested in setting up a study of a new experimental drug for leukemia. You intend to compare it with a standard treatment. Your Ho basically is the experimental drug is no better than standard treatment. If a and [3 could be controlled statistically, which set of values would you prefer if you were a physician going to give the drug to a patient? 1. o= .05 B= .05 2. a: .10 B: .001 3. o= .20 B: .0005 If u = 0, we reject Ho. o=0and|3=0ifwesamplethe If someone told you that u + B = 1, then that would imply I Suppose I was working as an inspector in a parachute factory. I test each one to make sure it works. My H0 is: the parachutes works. My H1 is: the parachute is bad. Here, in terms of this problem, making an a error means what about parachutes? and making a [3 error means what about parachutes? Which is worse in this case, a or [3- error
