A coin is equally likely to be either Biys or Ba/s. To figure out the bias, we toss the coin 99 times and declare By/s if the number of heads is less than 49.5 and B2/3 otherwise. Bound the error probability using the Chernoff bound derived in lecture video (in its final form, after simplifcation)
Coin 1 has bias p1, coin 2 has bias p2, coin 3 has bias p3. All coin flips are independent. We choose one of the three coins at random (each coin equally likely). Then we toss n times. Let's say K is A RANDOM VARIABLE the indicates the number of heads. Can we approximate K as normal? If yes what is mean and variance in this case? Let's say we toss coin 1 n1 times, coin 2 n2 times and...
-3 points Suppose we have a fair coin that is equally likely to come up heads or tails (a) The coin is flipped 3 times. How many ways can we get exactly 1 head? (b) The coin is flipped 5 times. How many ways can we get exactly 2 tails? (c) The coin is flipped 4 times. How many ways can we get at least 3 tails?
1. You are told that .coin has probability of a Head either p 1/3 or p = 2/3. You must a test Ho p= Ha p You toss the coin 3 times and get Y Heads. You decide to reject Ho in favor of Ha if Y = 2 or Y 3. (Note that the count of Heads Y is the CSS for p.) What are the two error probabilities a and B for this test? What is the power...
