   Question

   Suppose a researcher has four averages over which she wants to run a multiple comparison confidence interval. There are six possible differences between averages and thus six confidence intervals. Now, for these six confidence intervals that

   
   
   1. FALSE: The probability is (0.95)6 that the true differences are within the limits found.
   2. TRUE: The probability is about 0.95 that the true differences are within the limits found.
   3. FALSE: For each interval separately, the probability is 0.95 that the true difference is within the limits found.
   
   
   1. The probability (0.95)6 is that the true differences are within the limits found…: Incorrect
   2. The probability is about 0.95 that the true differences are within the limits found…: Correct
   3. For each interval separately, the probability is 0.95 that the true difference is within the limits found…: Incorrect
