sample of 180 six-year-old girls weighed between 2003 and 2006 had an average weight of 50.4 pounds. Assume the population standard deviation is a=16.5 pounds. Can you conclude that the mean weight of six-year-old girls is higher in 2006 than in 2002? Use the a=0.10 level of significance and the P-value method with the TI-84 calculator. Espa Part 1 of 4 State the appropriate null and alternate hypotheses. Hou=49.3 H: >49.3 The hypothesis test is a right-tailed test. Part: 1/4 Part 2 of 4 Compute the P-value. Round your answer to at least four decimal places. 8 E C al
