A study addressed the issue of whether pregnant women can correctly guess the gender of the baby. Among 110 recruited subjects, 53.6% of them correctly guessed the gender of the baby. Use these sample data to test the claim that the success rate of such guesses is no different than the 50% success rate expected with random chance guesses. Use a 0.01 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, and P-value, then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Identify the null and alternative hypotheses. Choose the correct answer below.
