Suppose a confidence interval for the difference in mean weight loss for two different weight loss programs (Program 1  Program 2) is entirely above zero. What does this mean?
 a. We can't say with any confidence that there is a difference in mean weight loss for the populations of people on these two programs.
  b. We can say with confidence that there is a difference in mean weight loss for the populations of people on these two programs; further, we can say that the average weight loss on Program 1 is higher.
  c. We can say with confidence that there is a difference in mean weight loss for the populations of people on these two programs; further, we can say that the average weight loss on Program 2 is higher.
  d. None of the above.
