10/25 Becky's statistics teacher was teaching the class how to perform the z-test for a proportion. Becky was bored because she had already mastered the test, so she decided to see if the coin she had in her pocket would come up heads or tails in a truly random fashion when flipped. She discretely flipped the coin 30 times and got heads 18 times. Becky conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of heads is different from 50%. Which answer choice shows the correct null and alternative hypotheses for this test? Select the correct answer below: Ho p=0.6; Ha p > 0.6, which is a right-tailed test. O Hop = 0.5; Ha: p < 0.5, which is a left-tailed test. Hn=06 H n06 which is a two-tailed test
