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 1917 2211 2775 2771 2342 1876 2737 2352 2149 2271
p 2068 2355 2796 2874 2366 1909 2889 2431 2196 2416
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 the p-value. use μp − μb. round your test statistic to two decimal places and your p-value to three decimal places.)
t=
df= 9
p-value= 0.002
i need in solving for the test statistic. my initial answers were: -3.59, 3.59, -5.1, 5.1.
