1. Do people actually prefer Pepsi or Coke in a taste test?

2. Can people correctly identify Pepsi versus Coke?

3. Are people consistent with their prior preference? In other words, do they prefer the

same cola in their taste test that they had previously indicated was their preferred cola?

At first i was going to use two-tailed tests for all three. but then i started thinking maybe number 1 was a one-tailed test. now i'm really confused.
