population. The 9595% confidence interval for the population standard deviation sigmaσ is (0.02720.0272,0.04340.0434). The population standard deviation of the volumes of the bottles' contents should be less than 0.0350.035 fluid ounce. Does the confidence interval for sigmaσ suggest that the variation in the volumes of the bottles' contents is at an acceptable level? Explain your reasoning.
Question
Answer:
Answer:does not suggest.Step-by-step explanation:Given that 95% confidence interval for the population standard deviation [tex]\sigma = (0.0272,0.0434).[/tex]Our hypotheses are:[tex]H_0: \sigma = 0.035\\H_a: \sigma <0.035\\[/tex](Left tailed test )The confidence interval contains the value in null hypothesis as 0.035This implies that null hypothesis is rightSo we accept null hypothesis.The confidence interval for sigmaσ suggest that the variation in the volumes of the bottles' contents isnot at an acceptable level, because it is not evident that sigma <0.035
