Breast feeding sometimes results in a temporary loss of bone mass as calcium is depleted in the mother's body to provide for milk production. An investigation gave the following data on total body bone mineral content (g) for a sample of mothers both during breast feeding (B) and in the postweaning period (P).

Question

Breast feeding sometimes results in a temporary loss of bone mass as calcium is depleted in the mother's body to provide for milk production. An investigation gave the following data on total body bone mineral content (g) for a sample of mothers both during breast feeding (B) and in the postweaning period (P).
Subject	1	2	3	4	5	6	7	8	9	10
B	2516	2087	2707	2376	2253	2311	2591	2195	2574	2117
P	2560	2164	2736	2465	2357	2505	2617	2218	2773	2195
Do the data suggest that true average total body bone mineral content during postweaning exceeds that during breast feeding by more than 25 g? State and test the appropriate hypotheses using a significance level of .05. (Use a statistical computer package to calculate P-value.)
t	=	 	(Round the answer to two decimal places.)
df	=	 
P-value	=	 	(Round the answer to three decimal places.)
