A sаmple оf 20 fuel cаnisters is tаken frоm a filling system at a fuel prоduction facility. The system is responsible for filling the canisters with a precise amount of fuel. The variance in the fill volume of the sample is found to be 0.0153 (gallons)². The company has set a quality control standard, where the variance in fill volume should not exceed 0.01 (gallons)². If it does an unacceptable proportion of canisters will be underfilled or overfilled, which could impact customer satisfaction or regulatory compliance. The facility's industrial engineer conducts a hypothesis test to assess whether the machine is operating within acceptable limits. The hypotheses are as follows: H₀: σ² = 0.01 (The variance in fill volume is within acceptable limits) H₁: σ² > 0.01 (The variance in fill volume exceeds the acceptable limit causing underfilled or overfilled canisters) The test is performed at a significance level of α = 0.05. The computer output is given below. table.PNG a) Is this a one-sided or two-sided test? b) Is there evidence in the sample data to suggest that the facility has a problem with underfilled or overfilled canisters? Use the P-value approach. c) Is there evidence in the sample data to suggest that the facility has a problem with underfilled or overfilled canisters? Use the fixed-level test. d) Explain how we can reach the same conclusion using the lower 95% confidence bound for variance given in the output.
