Evaluate β for the alternatives p = 0.5 and p = 0.7.

Beta is The probability of Type 2 error.

I tried to use the binomial distribution with n=15 and p=.5 and .7 to get P(6<=x<=12|p=.5) and use 12 and 6 for x and substract the results but I can't get the correct answers which are 0.8454 for p=.5, and 0.8695 for p=.7

Is there another way of doing it? Are me x's right for the binomial distributio right?
