Construct a situation for which you can test null and alternative hypotheses for a population proportion. For example, you could see whether you can flip a coin in a manner so as to bias it in favor of heads. Or you could conduct an ESP test in which you ask someone to guess the suits in a deck of cards. (To do the latter experiment properly, you must replace the card and shuffle each time so you don’t change the probability of each suit by having only a partial deck, and you must separate the “sender” and “receiver” to rule out normal communication.) Collect data for a sample of at least size 100. Carry out the test. Make sure you follow the four steps given in Section 22.2, and be explicit about your hypotheses, your decision and the reasoning behind your decision.
