Briefly summarize the experimental design for deciding whether a proposed treatment should go on for further study. Note where independence came into play. If you were more conservative and reject the treatment only if the probability that it is 30% effective is less than .05 what does the math tell you about whether you would more than 14 patients or fewer than 14 patients?
It would help if you proofread your questions before you posted them.
What experimental design?
"...you would ????? more than 14 patients…."
