A random sample of 777 births in New York State included 384 boys. Use a 0.05 significance level to test the claim that 51.2% of newborn babies are boys. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. Do the results provide strong evidence against the belief that 51.2% of newborn babies are boys? Let p denote the population proportion of all newborn babies in New York State that are boys. Identify the null and alternative hypotheses to test the claim that 51.2% of newborn babies are boys. $H_0: p = 0.512$ $H_1: p \neq 0.512$ (Type integers or decimals. Do not round.) Identify the test statistic. $z = -0.94$ (Round to two decimal places as needed.)

The federal government would like to test the hypothesis that the average age of men filing for Social Security is higher than the average age of women set using $\alpha = 0.05$ with the following data: \begin{tabular}{|l|l|l|} \hline & Men & Women \\ \hline Sample mean & 64.5 years & 63.6 years \\ Sample size & 35 & 39 \\ Population standard deviation & 3.0 years & 3.5 years \\ \hline \end{tabular} If Population 1 is defined as men and Population 2 is defined as women, the correct hypothesis statement for this hypothesis test would be $\circ$ $H_0: \mu_2 - \mu_1 \leq 0; H_1: \mu_2 - \mu_1 > 0$ $\circ$ $H_0: \mu_1 - \mu_2 = 0; H_1: \mu_1 - \mu_2 = 0$ $\circ$ $H_0: \mu_1 - \mu_2 \leq 0; H_1: \mu_1 - \mu_2 > 0$ $\circ$ $H_0: \mu_1 - \mu_2 \geq 0; H_1: \mu_1 - \mu_2 < 0$
