Question

Breast‑feeding mothers secrete calcium into their milk. Some of the calcium may come from their bones, so mothers may lose bone mineral. Researchers measured the percent change in mineral content of the spines of 47 mothers during three months of breast‑feeding. The data are given in the table.

Percent Change in Mineral Content

−4.7	−2.5	−4.9	−2.7	−0.8	−5.3	−8.3	−2.1	−6.8	−4.3
2.2	−7.8	−3.1	−1.0	−6.5	−1.8	−5.2	−5.7	−7.0	−2.2

The researchers are willing to consider these 47 women to be an SRS from the population of all nursing mothers. Suppose that the percentage change in this population has standardard deviation ?=2.5% vitamin D‑receptor genotype," American Journal of Clinical Nutrition, 67 (1998), pp. 685–692.

Use a 90% confidence interval to estimate the mean percent change in the population.
