It has been reported that the 1-Euro coin is more likely to yield Heads (i.e., the probability is greater than 0.5) when flipped than it is to yield Tails. An experiment of 400 flips yielded 212 Heads. Let p be the probability of getting a head when flipping a 1-Euro coin. We can consider p as the population proportion as it is the proportion of Heads occur in infinitely many tosses.
To test this claim, what are the null and alternative hypotheses?
