A container of car antifreeze is supposed The whole three 3785 mL of the liquid. Realizing that fluctuations are in inevitable, Quality control manager of the Taconic chemical company wants to be quite sure that the standard deviation is less than 30 mL otherwise some containers would overflow while others would not have enough of the coolant she selects a simple random sample of 24 containers and find that mean it's three 789 mL in the scanner deviation is 42.8 mL use the sample results to construct a 99% confidence interval for the true value of Sigma does this confidence interval suggest that the variation is that an acceptable level?
