A 95% confidence interval for the standard deviation of time until failure (in years) of a household appliance is found to be between 1.5 years and 6.4 years. What would be a reasonable conclusion from this statement? A. The sample size was far too low for this to be a reasonable construction B. The mean time until failure is between 2.25 squared years and 40.96 squared years C. A 99% confidence interval would surpass 10 years beyond the mean for the upper estimate D. An appliance that fails within 2 years of the mean failure time would not be considered unusual
