You work for the U.S. Food and Drug Administration. You have gotten word that a drug manufacturing is accurately reporting the contents of their liquid cold medication. Under Federal Regulations, "Variation from stated quantity of contents shall not be unreasonably large" (see section q of the regulation by clicking here). The company that produces the cold medication is claiming that each bottle contains 355 milliliters of medication, which is about 12 fluid ounces. In order to determine if they are accurate in their reporting you decide to randomly select 20 different bottles of cold medication and measure the amount of cold medication in each bottle (in milliliters). The results of each sample are shown below. Bottle Number Milliliters 1 2 344 359 3 4 5 6 7 8 9 10 357 349 345 359 355 354 345 345 Bottle Number 11 12 Milliliters 13 14 15 16 17 18 19 20 355 353 360 344 355 342 353 354 350 346

Record the result below in the form of (#, #). Round your final answer to two decimal places. b) Is the company putting the claimed 355 milliliters of cold medication in their bottles? Explain. Yes, because 355 is inside of the confidence interval. Yes, because 355 is not inside the confidence interval. No, because 355 is inside the confidence interval. No, because 355 is not inside the confidence interval.
