A test is being conducted to test the difference between two population means using data that are gathered from a matched pairs experiment. If the paired differences are normal, then the distribution used for testing is the:
    |  | 
  |    |  | b. Student t-distribution. |  |  | 
  |    |  | c. binomial distribution. |  |  |

It wil be a Student\'s t -distribution,
