Question 2

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? A) No, since the value 31.2 does not fall in the 95 confidence interval.
  B) Yes, since the value 31.2 does fall in the 95 confidence interval.
  C) Yes, since the value 31.2 does not fall in the 95 confidence interval.
  D) No, since the value 31.2 does fall in the 95 confidence interval.
