[5](8) The Brazil vending machine dispenses coffee, and a random sample of 27 filled cups have contents with a mean of 7.14 oz and a standard deviation of 0.17 oz. Use a 0.05 significance level to test the claim that the machine dispenses amount with a standard deviation greater than the standard deviation of 0.15 oz specified bin the machine design. a) Set up the hypotheses for a standard deviation (o). Ho H1: b) Find the critical value(s). c) Calculate the value of the test statistic. (n - 1)$2 XSTAT = 02 d) Perform the hypothesis test. e) Make the decision
