Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.6 bpm. For a random sample of 168 adult males, the mean pulse rate is 69.2 bpm and the standard deviation is 10.8 bpm. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. SEEM (Type an integer or a decimal. Do not round.) A study addressed the issue of whether pregnant women can correctly guess the gender of the baby. Among 120 recruited subjects, 54.2% 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 0.05 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. O A. Ho: p = 0.5 O B. Ho: p = 0.542 H,: p > 0.5 H1: p 0.542 O E. Ho: p = 0.542 OF. Ho: p = 0.5 H,: p #0.542 H1: p 0.2 OD. Ho: p = 0.2 H1: p = 0.2 H1: p > 0.2 OE. Ho: p = 0.2 OF. Ho: p # 0.2 H1: p
