Breast feeding sometimes results in a temporary loss of bone mass as calcium is depleted in the mother's body to provide formilk production. An investigation gave the following data on total body bone mineral content (g) for a sample of mothersboth during breast feeding (B) and in the postweaning period (P).Subject 1 2 3 4 5 6 7 8 9 102368 2181 2007 2362 2684 2671 2142 2774 2097 25402447 2354 2195 2500 2745 2858 2243 2824 2297 2668Do the data suggest that true average total body bone mineral content during postweaning exceeds that during breastfeeding by more than 25 g?

Have you ever been frustrated because you could not get a container of some sort to release the last bit of its contents? An article reported on an investigation of this issue for various consumer products. Suppose five 6.0 oz tubes of toothpaste of a particular brand are randomly selected and squeezed until no more toothpaste will come out. Then each tube is cut open and the amount remaining is weighed, resulting in the following data: 0.52, 0.63, 0.43, 0.5, 0.35. Does it appear that the true average amount left is less than 10% of the advertised net contents? USE SALT (a) Check the validity of any assumptions necessary for testing the appropriate hypotheses.

Hyperhidrosis is a stressful medical condition characterized by chronic excessive sweating. Botox was approved for treatment of hyperhidrosis in adults in 2004. A clinical trial examined the effectiveness of Botox for excessive armpit sweating in teenagers aged 12 to 17 years. Participants received either a Botox injection or a placebo injection (a simple saline solution) and were examined four weeks later to see if their sweating had been reduced. Here are the study's findings: Botox Placebo Total Reduced Confidence Interval: 72 52 124 Not Reduced 28 We are 95% confident that there is hyperhidrosis who experienced a reduction in sweating. 148 176 Total 100 200 - Construct a 95% confidence interval for p₁ - P2 where p₁ denotes the proportion of teenagers who experienced a reduction in sweating in the Botox group and p2 denotes the proportion of teenagers who experienced a reduction in sweating in the placebo group.
