A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 3% margin of error at a 95% confidence level, what size of sample is needed? When finding the z-value, round it to four decimal places. You work for the U.S. Food and Drug Administration. You have gotten word that a drug manufacturing is not accurately reporting the contents of their liquid cold medication. Under Federal Regulations, "Variations from stated quantity of contents shall not be unreasonably large" (see section q of the regulation by clicking here EU. The company that produces the cold medication is claiming that each bottle contains 355 milliliters of cold 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 1 2 3 6 7 8 9 10 Milli liters 352 353 350 342 340 349 348 340 Bottle Number 11 12 13 14 15 17 18 19 20 Milli liters 342 352 360 348 346 349 343 349 348 a) Use the data shown above to construct a 98% confidence interval estimate for the mean amount of cold medication the company is putting in their bottles. 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. 0 Yes, because 355 is inside of the confidence interval. 0 Yes, because 355 is not inside the confidence interval. 0 No, because 355 is inside the confidence interval. 0 No, because 355 is not inside the confidence interval.
