10) A set of data was collected involving the number of defective items found in a random sample of 46 cases of light bulbs produced during a morning shift at a plant. A manager wants to know if the mean number of defective bulbs per case is greater than 20 during the morning shift. She will make her decision using a test with a level of significance of 0.10. The following information was determined for the sample of 46 cases: n = 46; Arithmetic Mean = 28.00; Standard Deviation = 25.92; Standard Error = 3.82; Null Hypothesis: H0: μ ≤ 20 versus H1: μ > 20; α = 0.10; df = 45; T Test Statistic = 2.09; One-Tail Test Upper Critical Value = 1.3006; p-value = 0.021; Decision = Reject. True or False: The null hypothesis would be rejected if a 1% probability of committing a Type I error is allowed. TRUE OR FALSE

Answer #1

as we can see from above output that p value=0.021 is greater than 1% level of significance ; therefore we can not reject null hypothesis at 1% level

hence False

    Example 8.4 An automobile model is known to sustain no visible damage 25% of the time in 10-mph crash tests. A modified bumper design has been proposed in an effort to increase this percentage. Let p denote the proportion of all 10-mph crashes with this new bumper that result in no visible damage. The hypotheses to be tested are Ho: P = 0.25 (no improvement) versus Ha: p ? ? 0.25. The test will be based on an experiment involving...
