Lactation promotes a temporary loss of bone mass to provide adequate amounts of calcium for milk production. A paper gave the following data on total body bone mineral content (TBBMC) (g) for a sample both during lactation (L) and in the postweaning period (P). Subject 5 1 2 3 4 6 7 8 9 10 L 1927 2546 2825 1921 1628 2175 2111 2621 1843 2544 P 2127 2885 2895 1945 1750 2181 2164 2625 2006 2626 (a) Does the data suggest that true average total body bone mineral content during postweaning exceeds that during lactation by more than 25 g? State and test the appropriate hypotheses using a significance level of 0.05. [Note: The appropriate normal probability plot shows some curvature but not enough to cast substantial doubt on a normality assumption.] (Use H₁ = μ₁-ML.) OH-25 HD 25 Ho HD25 H: ≤25 ⒸH₂ -25 H: 25 ⒸH: #p=25 H₂> 25 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = -3.98 P-value = 0.005 X x State the conclusion in the problem context. O Fail to reject Ho. The data suggests that the true average total body bone mineral content during postweaning exceeds that during lactation by more than 25 g. O Reject H. The data suggests that the true average total body bone mineral content during postweaning does not exceed that during lactation by more than 25 g. O Fail to reject Ho. The data suggests that the true average total body bone mineral content during postweaning does not exceed that during lactation by more than 25 g. ⒸReject Ho. The data suggests that the true average total body bone mineral content during postweaning exceeds that during lactation more than 25 g. ✓ (b) Calculate an upper confidence bound using a 95% confidence level for the true average difference between TBBMC during postweaning and during lactation.
