Confidence Interval /Margin of Error The Food and Drug Administration (FDA] recommended the general cold medicine should have 600 milligrams of acetaminophen per fluid ounce as an active ingredient. FDA tested 100 samples of the medicine from several brands to make an inference to the population. FDA found that the sample mean of the amount of acetaminophen in the sample is 597 milligrams. The standard deviation is 20 milligrams. The sample is normally distributed. Calculate and input the margin of error (m) of 95% confidence interval in the blank below. (Round the answer in two decimal places) Based on the calculated margin of error (m], construct the 95% confidence interval for the estimate. What is the lower limit?
