Two machines are used for filling plastic bottles with a net volume of 16.0 ounces. The fill volume can be assumed to be normal with standard deviation o₂ = 0.020 and ₂ = 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. Machine 1: 16.03, 16.01, 16.04, 15.96, 16.05, 15.98, 16.05, 16.02, 16.02, 15.99 Machine 2: 16.02, 16.03, 15.97, 16.04, 15.96, 16.02, 16.01, 16.01, 15.99, 16.00 Is the engineer correct that both machines fill to same mean net volume? Use a = 0.10. O a. Fail to reject the Null Hypothesis. -1.65 < 0.99 < 1.65 b. None among the choices O c. Fail to reject the Null Hypothesis
