In Country A, the population mean height for 3-year-old boys is 37 inches. Suppose a random sample of 15 3-year-old boys from Country B showed a sample mean of 36.2 inches with a standard deviation of 3 inches. The boys were independently sampled. Assume that heights are Normally distributed in the population. Complete parts a through c below. a. Determine whether the population mean for Country B boys is significantly different from the Country A mean. Use a significance level of 0.05. Which of the following correctly states Ho and H₂? A. D. Ho:μ ≥37 Ha:μ<37 Ho: μ = 37 Ha: μ#37 Find the test statistic. B. O E. Ho: μ = 37 Ha: μ<37 Ho: μ#37 Ha: μ = 37 t= (Type an integer or decimal rounded to two decimal places as needed.) Find the p-value. р (Type an integer or decimal rounded to three decimal places as needed.) Reject or do not reject Ho. Choose the correct answer below. Ho: μ>37 C. Ha: μ≤37 O F. Ho: μ = 37 Ha: μ>37
