    1. The problem statement, all variables and given/known data

    Independent random samples selected. One has 15 points, one has 16.

    It asks "is there evidence μ2 - μ1 > 10? Test at 0.01 level of significance.

    2. The attempt at a solution

    There are 29 degrees of freedom. The t-score at 0.01 for 29 is 2.462.

    I just don't get how I test whether 1. The problem statement, all variables and given/known data

    1) Do I just find the t-score, find μ2 - μ1, and see how many standard deviations it takes to get 10, and i.e. if it takes over 3, say very little probablity etc?
