How the heck do I enter the following (red highlighted) into a calculator to figure it out?
Basically the problem(s) I'm trying to figure out are:
1) A basketball player tell his coach that he raised his foul-shot profiency from 45% to 65%. Dubious, the coach asks him to take 10 shots, and is surprised when the player makes 9 out of 10.
Suppose the player is really no better than before - still a 45% shooter. Whats the probability that he could hit 9 out of 10 shots anyways?
If the player really can hit 65% now, and it takes at least 9 out of 10 succesful shots to convice the coach, whats the power of the test?
