      int number;
      double mean = ComputeMean(scores, out number);
      Console.WriteLine("Average test score: {0:N2} (n={1})", mean, number);
   }

   private static double ComputeMean(Tuple<string, Nullable<int>>[] scores, out int n) 
   {
      n = 0;      
      int sum = 0;
      foreach (var score in scores)
      {
         if (score.Item2.HasValue)
         { 
            n += 1;
            sum += score.Item2.Value;
         }
