You know that with a 'fair coin', the population proportion of heads in 50 coin flips should be 0.50 (a 'fair coin' is a coin that when flipped will land heads up 50% of the time and will land tails up 50% of the time). You are going to use coin flips to decide whether someone is assigned to one of two groups in an experiment and must make sure that the coin being used is a 'fair coin'. You decide to test whether the proportion of heads in 50 coin flips is 0.50 or different from 0.50 in the population of all coin flips. Indicate your null and alternative hypotheses for the proportion of heads in all coin flips, first in words and then using proper statistical notation (p for a population proportion: Ho for the null hypothesis and Ha for the alternative hypothesis; indicate your null value in your hypotheses)
