Chapter 5, Problem 18(choose chapter or problem)
Boxes of nails contain 100 nails each. A sample of 10 boxes is drawn, and each of the boxes is weighed. The average weight is \(1500 \mathrm{~g}\) and the standard deviation is
\(5 \mathrm{~g}\). Assume the weight of the box itself is negligible, so that all the weight is due to the nails in the box.
Let \(\mu_{\text {box }}\) denote the mean weight of a box of nails. Find a 95% confidence interval for \(\mu \text { box }\).
Let \(\mu_{\text {nail }}\) denote the mean weight of a nail. Express μnail in terms of
\(\mu \text { box }\).
Find a 95% confidence interval for \(\mu_{\text {nail }}\).
