A coin manufacturer claims that he has produced a biased coin with P(H) = 0.4 and P(T) = 0.6 where P(H) denotes the probability of the coin landing on heads and P(T) denotes the probability of the coin landing on tails. Brad takes this coin and tosses it 10 times. He obtains heads on the first 8 tosses and tails on the last two tosses. He decides to do a hypothesis test to see if there is enough evidence to reject the manufacturer’s claim. Which one of the following statements should he adopt as his null hypothesis? 1) P(H) = 0.4 2) P(H) = 0.6 3) P(H) = 0.8 4) P(H) = 0.2 5) P(H) = 0.5

Question
A coin manufacturer claims that he has produced a biased coin with P(H) = 0.4 and P(T) = 0.6 where P(H) denotes the probability of the coin landing on heads and P(T) denotes the probability of the coin landing on tails. Brad takes this coin and tosses it 10 times. He obtains heads on the first 8 tosses and tails on the last two tosses. He decides to do a hypothesis test to see if there is enough evidence to reject the manufacturer’s claim. Which one of the following statements should he adopt as his null hypothesis?
1) P(H) = 0.4
2) P(H) = 0.6
3) P(H) = 0.8
4) P(H) = 0.2
5) P(H) = 0.5
