A manufacturer of coffee vending machines has designed a new, less expensive machine. The current machine is known to dispense (into cups) an average of 5 fl. oz., with a standard deviation of .2 fl. oz. When the new machine is tested using 15 cups, the mean and the standard deviation of the fills are found to be 5 fl. oz. and .216 fl. oz. Test Hg: o = .2 versus H,: o + .2 at levels of significance .05 and .01. Assume normality. (Round your answer to 4 decimal places.)

Question
A manufacturer of coffee vending machines has designed a new, less expensive machine. The current machine is known to dispense
(into cups) an average of 5 fl. oz., with a standard deviation of .2 fl. oz. When the new machine is tested using 15 cups, the mean and
the standard deviation of the fills are found to be 5 fl. oz. and .216 fl. oz. Test Hg: o = .2 versus H,: o + .2 at levels of significance .05
and .01. Assume normality. (Round your answer to 4 decimal places.)
chi-square
H0 for a = 0.05.
H0 for a = 0.01.
