5. Two machines are used for filling plastic bottles to a net volume of 16.0 ounces. A member of the quality engineering staff suspects that the machines are not filling to the same net volume. An experiment was conducted to obtain random samples (n=10) from each machine. The data are shown below. Analyze this data to determine if the quality engineer is correct. Begin by performing an appropriate test to determine if the variances can be assumed equal (verify necessary...

2side Hypothesis Testing_03 (two independent sam machines are used for filling plastic battle with a new volume of 16.0 ounces. The fill volume can be assumed was with standard deviations d. 0.020 and 0.025 ounces. A member of the quality engineering staff that both machines fill to the same mean net volume, whether or not this volume is 16.0 ounces. random sample of 10 bottles is taken from the output of each machine: Machine 01 16.03 16.01 16.04 15.96 16.05...
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 o1 = 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 Machine 1 16.03 16.01 16.04 15.96 16.05...
The melting points of two alloys used in formulating solder were investigated by melting 21 samples of each material. The sample mean and standard deviation for alloy 1 was 420.48 and 2.34 respectively, and for alloy 2 they were 425 and 2.5 respectively. Do the sample data support the claim that both alloys have the same melting point? Use a fixed-level test with alpha=0.05 and assume that both populations are normally distributed and have the same standard deviation. Provide the...
