If we use the data given in Exercise 1, we get this 90% confidence interval estimate of the standard deviation of weights with the new minting process: 0.01686 g

Exercise 1

Assume that the U.S. Mint manufactures dollar coins so that the standard deviation is 0.04000 g (based on Data Set 40 “Coin Weights” in Appendix B). Listed below are weights (grams) of dollar coins manufactured with a new process designed to decrease the standard deviation so that it is less than 0.04000 g. This sample has these summary statistics: n = 16, X̅ = 8.06576 g, s = 0.02176 g. If we want to use a 0.05 significance level to test the claim that the sample is from a population with a standard deviation less than 0.04000 g, what requirements must be satisfied? How does the normality requirement for a hypothesis test of a claim about a standard deviation differ from the normality requirement for a hypothesis test of a claim about a mean? 8.0652 8.0548 8.0754 8.0545 8.0334 8.0126 8.0758 8.0517 8.0730 8.1084 8.0678 8.0808

8.0652 8.0548 8.0754 8.0545 8.0334 8.0126 8.0758 8.0517 8.0730 8.1084 8.0678 8.0808 8.0680 8.0818 8.0684 8.0806
