20. (8 points) Quarters are currently minted with weights having a mean of 5.670 grams and a standard deviation of 0.062 gram. New equipment is being tested in an attempt to improve quality by reducing variation. A random sample of 24 quarters is obtained from those manufactured with the new equipment, and this sample has a standard deviation of 0.049 gram. Use a = 0.05 to test the claim these quarters have weights with a standard deviation less than 0.062 g. Use Traditional method. Parameter's name and symbol: Claim: State the given data: Circle the appropriate test: z-test t-test x2-test 1 State the null and alternative hypotheses, indicate the Tail-test, and identify the claim. Ho: H1: 2 Find the critical value(s). Show your work! 3 Find the test value. Show your work! 4 Make the decision and justify it (circle one): Reject Ho or Do not reject Ho 5 Summarize the result.
