It is known that one of two given coins is fair, and that the other coin has probability

of coming up heads when flipped. It is desired to determine which of the coins is the fair coin. The coins, tossed simultaneously and independently, produce a sequential sample, where Xi and 1'; are each o or I, according as to whether the respective coin is a tail or a head. Determine the form of an SPRT for this problem, and calculate (exactly) the corresponding

Prove that (7.73) is true under the condition that
