Transcribed Image Text: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 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 0.10
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?
