A 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 .17 oz. Use a .05 significance level to test the claim that the true mean fill for all cups is greater than 7 oz. You may assume a normal population (n < 30 here; assume that assumption was checked). Fill in and show calculations.

Ho : null hypothesis                                                     S.V.: sample value

Ha : alternative hypothesis                                                     Dec.: decision

T.S.: test formula                                                      Concl.: conclusion

R.R. (draw and label value): Rejection region

                                                            p-value (indicate one)   > .05   or   < .05

    Question: An automatic coffee machine dispenses cups of coffee whose volume per cup varies normally and should have the mean μ = 10 oz if it is working correctly. A quality-control researcher randomly selects 8 cups of coffee from the machine and finds that in this sample the mean volume is 9.92 oz. and the standard deviation is 0.23 oz. In this problem, we have made slight changes to the "coffee machine" story above. In which of the options below...
