   Suppose a researcher has four averages for which she wants to calculate multiple comparison Tukey confidence intervals wants to calculate. There are four averages a total of six possible differences between averages and therefore six confidence intervals. For comparison, the researcher also calculates comparison also calculates the ordinary 95% confidence intervals. Two of these ordinary 95% confidence intervals are (4, 8) and (13, 17). What are now possible Tukey 95% confidence intervals that correspond to the above two ordinary confidence intervals?

   
   
   1. TRUE: (3.5, 8.5) and (12.5, 17.5)
   2. FALSE: (4.5, 7.5) and (13.5, 16.5)
   3. FALSE: (4, 7) and (12, 18)
   
   
   1. (3.5, 8.5) and (12.5, 17.5): Correct
   2. (4.5, 7.5) and (13.5, 16.5): Incorrect
   3. (4, 7) and (12, 18): Incorrect
