Extracted text: Country A, the population mean height for 10-year-old girls is 54.3 inches with a standard deviation of 2.3 inches. Suppose a random sample of 15 10-year-old girls m Country B is taken and that these girls had a sample mean height of 53.9 inches with a standard deviation of 2.6 inches. Assume that heights are Normally stributed. Complete parts (a) through (c) below. Now suppose the sample consists of 50 girls instead of 15. Repeat the test. etermine the null and alternative hypotheses. Choose the correct choice below. - A. Ho: µ= 54.3 Ο Β. H : μ= 54.3 O C.
