A coin is suspected of bias towards heads, so a test is made of the hypothesis H0: p=1/2 against H1:p>1/2, where p is the probability of heads. The test is to count the number of heads, X, in 10 tosses of the coin, and reject H0 if X=8, 9, or 10.
Show that the power function for this test is given by: p^8(45-80p+36p^2)
I have no idea how to start. I know that the power function means: P(reject H0 given H0 is false) but i don't know how to continue.
Any help would be very much appreciated.
Thank you
