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 gave a mean nicotine content of 28.5 milligrams and standard deviation of 2.2 milligrams for a sample of n = 9 cigarettes. The FDA claims that the mean nicotine content exceeds 31.2 milligrams for this brand of cigarette, and their stated reliability is 95%. Do you agree?
◦ No, since the value 31.2 does fall in the 95% confidence interval.
◦ Yes, since the value 31.2 does fall in the 95% confidence interval.
◦ Yes, since the value 31.2 does not fall in the 95% confidence interval.
◦ No, since the value 31.2 does not fall in the 95% confidence interval.
