To help consumers assess the risks they are taking, the Food and Drug Administration (FDA) publishes the amount of nicotine found in all commercial brands of cigarettes. A new cigarette has recently been marketed. The FDA tests on this cigarette yielded mean nicotine content of 27.3 milligrams and standard deviation of 2.1 milligrams for a sample of n = 9 cigarettes. Construct a 95% confidence interval for the mean nicotine content of this brand of cigarette. O 27.3 + 1.614 O 27.3 + 1.712 O 27.3 + 1.679 O 27.3 ± 1.583
