P(Type 1 error) = P(Reject Ho|p = 1/2) = P(X > Some critical value | given p = 1/2) and this is <= 1/8
ie P(X > Xc | p=1/2) <= 1/8
For the present binomial distribution with n = 3, this is satisfied only for X = 3.
Hence Xc = 3 and accept NULL for X = 0,1,2. Is this correct? I'm not sure I understand how Type II error features here, sir.
