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 0.05 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: a=0.0410 g and H₁: o<0.0410 g. For this sample data, we get a P-value of 0.0038 when testing the claim that o<0.0410 g. Complete parts (a) through (c).
