mean is 7.4 mL, with a standard deviation of 0.79 mL. Calculate the margin of error and construct the 99% confidence interval for the true population mean dose that parents pour. We may assume that the sample standard deviation s is an accurate approximation of the population standard deviation a (i.e., s 0), given that the sample size is so large (n> 200). Standard Normal Distribution Table E Round to 3 significant digits mL Round to 2 decimal places Liquid suspensions are commonly used in children's medications. There is a concern about liquid suspensions around incorrect dosing, due to the imprecise nature of measuring out a dose. A sample of 350 parents are asked to pour out one dose (5 mL) of the medication in their usual way, and the amounts are measured. The sample mean is 7.4 mL, with a standard deviation of 0.79 mL. Calculate the margin of error and construct the 99% confidence interval for the true population mean dose that parents pour. We may assume that the sample standard deviation sis an accurate approximation of the population standard deviation o (i.e., s= 0), given that the sample size is so large (n> 200).
