Assume that the U.S. Mint manufactures dollar coins so that the standard deviation is 0.0410 g. The accompanying list contains weights (grams) of dollar coins manufactured with a new process designed to decrease the standard deviation so that it is less than 0.0410 g. This sample has these summary statistics: n = 16, x =8.066 g, s=0.02 g. A 0.10 significance level is used to test the claim that the sample is from a population with a standard deviation less than 0.0410 g. The null and alternative hypotheses are Ho: G= 0.0410 g and Hj: G
