5. DETAILS DEVORESTAT9 9.3.040. 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).

State and test the appropriate hypotheses using a significance level of 0.05.

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. (b) Calculate an upper confidence bound using a 95% confidence level for the true average difference between TBBMC during postweaning and during lactation. (Round your answer to two decimal places.) 9 (c) Does the (incorrect) use of the two-sample t test to test the hypotheses suggested in (a) lead to the same conclusion that you obtained there? Explain. Yes, if the two samples were independent, the result would be the same. No, if the two samples were independent, the result would not be the same. You may need to use the appropriate table in the Appendix of Tables to answer this question. DETAILS Submit Answer DEVORESTAT9 9.5.064.
