Two machines are used for filling plastic bottles with a net volume of 16.0 ounces. The fill volume can be assumed normal, with standard deviation 0₁ = 0.020 and 02 = 0.025 ounces. A member of the quality engineering staff suspects that both machines fill to the same mean net volume, whether or not this volume is 16.0 ounces. A random sample of 10 bottles is taken from the output of each machine. Use a = 0.10 Machine 1 Machine 2 16.67 16.29 16.87 16.29 15.43 16.19 16.49 15.46 16.04 15.56 16.51 15.92 16.54 15.88 16.99 15.49 16.09 16.78 16.39 16.91
