Two machines are used for filling small plastic bottles with a net volume of 16 ml. The fill volume is assumed to be normally distributed for both machines. The quality engi- neering staff believes that both machines fill to the same net volume. A random sample of 10 bottles is taken from the output of each machine to test this claim. The sample data can be summarised as: = Machine 1:₁ 16.015 ml, s₁ = 0.030 ml, Machine 2: ₂ = 16.005 ml, s2 = 0.025 ml This is not EXACTLY the same sample data as in Q9 of Seminar 9! Do you think that the quality engineers are correct? Perform an appropriate significance test using a = 0.01. Describe the strength of the evidence and state your conclusions using a clear and non-technical language. Two machines are used for filling small plastic bottles with a net volume of 16 ml.
