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 2 345 6 7 8 910 2389 1935 2024 2826 2157 1906 2131 2495 2102 2555 I:2 2410 2075 2148 2986 2173 1926 2230 2517 2282 2631 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 0.05 Use a statistical computer package to calculate e P va e sep Round your est statistic to two decimal places and the P-value to three decimal places.) t- df= 89 Conclusion O reject Ho fail to reject Ho

Explanation / Answer

The output of the test is as follows

t = 3.0184

df = 9

p = 0.00726

Conclusion : Reject H0
