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: nequals16, x overbarequals8.064 g, sequals0.03 g. A significance level is used to test the claim that the sample is from a population with a standard deviation less than 0.0410 g. If we want to use a 0.01 significance level and a parametric method to test the claim that the sample is from a population with a standard deviation less than 0.0410 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? LOADING...
